Install

How do I install the ExtensionDash MCP server?

ExtensionDash is a hosted endpoint at https://extensiondash.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Tool Tokens
add_competitor ~298

Start tracking a competitor for an extension. Takes the same store and external_id that search_store returns, so a result you just saw on a SERP can be promoted without looking anything up in between. Promoting a listing is what earns it a store fetch: its description, install count, rating and languages start being recorded, and its position is kept even on days it falls out of the results entirely. Where it ranks has been recorded all along, from the searches this account already runs — so a competitor added today arrives with history rather than starting from zero. The description is not available when this returns. Call list_competitors with the same extension_id until this competitor's status turns from "pending" to "scraped". At most 20 competitors per store, because each one costs a fetch of that store on every refresh. The two stores are counted separately: a full Chrome roster does not cost you a Firefox slot. Needs an ExtensionDash account. Without one, find_listing and get_store_listing still read any extension's current store page; sign up at https://extensiondash.com/signup and reconnect using the URL on your /profile page for anything else.

external_idstringyesChrome's 32-letter id or the AMO slug, exactly as search_store returns it.

No output schema declared.

No examples provided.

add_keyword ~361

Start tracking a search term for an extension. The term is added once per store the extension is listed in, and a rank fetch is enqueued for each store that was not already tracking it. The position is not available when this returns. Call list_keywords with the same extension_id until this term's status turns from "pending" to "scanned", or list_scrape_runs to watch the fetch itself — a fetch that fails shows up there, rather than as a position that never arrives. A term is tracked per store language. Tracking "ad blocker" in en and again in de gives two independent keywords with their own positions. Call list_keywords for the languages an extension already tracks. During the beta an extension tracks at most 15 keywords, counted per language: "ad blocker" in en and de is two of them. Past that this returns a limit error and remove_keyword has to free a slot first. Needs an ExtensionDash account. Without one, find_listing and get_store_listing still read any extension's current store page; sign up at https://extensiondash.com/signup and reconnect using the URL on your /profile page for anything else.

NameTypeReqDescription

termstringyesThe search term, e.g. "json viewer". Squished and lowercased before use.

No output schema declared.

No examples provided.

find_listing ~538

Turn an extension's NAME into the store id every other tool asks for. Start here whenever you were handed a name rather than an id or a store URL, which is what a person will normally give you. Matching is approximate: case, punctuation, word order and a missing word are all tolerated, so "image search anywhere" finds "Reverse Image Search Anywhere". This reads names already stored here. It is not a store search and reports no ranking -- for where an extension actually places on a term, use search_store. It starts no fetch, so it never returns "pending" and spends none of the store-egress budget; like every call here it is logged and counts against the rate limit. Every match carries `cached`. true means get_store_listing can serve that extension's page from cache right now, with no account. false says one thing only: this locale has no fresh guest-readable cache. For a guest that is a refusal. Signed in, the next call may answer "pending" while it fetches, or hand back older data marked stale while it refreshes, or report a recent fetch failure with no listing at all -- so read the status you get rather than assuming which of those it will be. `cached` is a promise about ONE locale -- the one you pass here, "en" by default -- because a Chrome listing read in German needs two fetches, English structure plus German copy. Ask with the locale you intend to read in, or the answer is about a different call than the one you make. Two extensions can share a name, so matches carry `publisher` to tell them apart when the store recorded one. A name too long to match in full is refused rather than trimmed, because trimming would report the words it dropped as matched. No match means this app has never seen that name -- guessing another spelling will not help. Use search_store if what you have is really a search phrase; otherwise ask the person you are working for for the extension's store URL or id, and pass that to get_store_listing.

NameTypeReqDescription
limitinteger–Most matches to return, best first. Defaults to 10.
localestring–Which locale `cached` should answer for. Defaults to "en". Does not change which names match.
namestringyesThe extension's name as you were given it, e.g. "Reverse Image Search Anywhere".
storestring–Restrict to one store. Both are searched when omitted.

No output schema declared.

No examples provided.

get_extension ~168

One extension in full: every store listing's latest numbers plus its tracked keywords and their current positions. locales lists every store language this extension tracks, with a keyword count each, so the keywords can be worked a language at a time. Use get_metrics_history or get_keyword_ranks for movement over time. This is the tracked view, built from what we have recorded. For an extension this account does not track, or for a listing in another language, use get_store_listing instead. Needs an ExtensionDash account. Without one, find_listing and get_store_listing still read any extension's current store page; sign up at https://extensiondash.com/signup and reconnect using the URL on your /profile page for anything else.

NameTypeReqDescription
extension_idintegeryesFrom list_extensions.

No output schema declared.

No examples provided.

get_keyword_ranks ~268

Daily search position history for an extension's tracked keywords, one series per term per store. Every point carries the depth it was scanned to, because a position only means something against the size of the pool it came from: #1 of 9 and #1 of 50 are different results. A null position means we searched that deep and this extension was not in the results. A term tracked in more than one store language comes back as one series per language — the same term is a different SERP in each. Needs an ExtensionDash account. Without one, find_listing and get_store_listing still read any extension's current store page; sign up at https://extensiondash.com/signup and reconnect using the URL on your /profile page for anything else.

NameTypeReqDescription
daysinteger–How far back to look. Defaults to 30.
extension_idintegeryesFrom list_extensions.
localestring–Store language, e.g. "de". Omit for every language. Canonicalised before use, so "DE" and "de" are one keyword and "pt-br" comes back as "pt-BR".
storestring––
termstring–One term. Omit for all of them.

No output schema declared.

No examples provided.

get_keyword_serp ~279

The search page for one of an extension's tracked keywords, as this account last recorded it — who was on it, in what order, and which way each of them moved over the past week. Read from recorded history, not from the store: no fetch, no waiting, no egress spent. Use search_store instead when you need what the store is showing right now; use this when you want movement, or the same page the dashboard is showing. Every row carries mine and competitor flags, so "who is above me and which of them am I already tracking" is one call. Positions always travel with depth_scanned, because #1 of 9 and #1 of 50 are different results. Needs an ExtensionDash account. Without one, find_listing and get_store_listing still read any extension's current store page; sign up at https://extensiondash.com/signup and reconnect using the URL on your /profile page for anything else.

storestringyes–
termstringyesA term this extension tracks. From list_keywords.
windowboolean–Return only the leaders and our own neighbourhood rather than the whole page. Defaults to false.

No output schema declared.

No examples provided.

get_metrics_history ~396

Daily-or-sparser history of an extension's numbers: user count, rating and ratings count, each as a map of ISO date to value. "listings" is this extension's own store listings; "competitors" is its roster from list_competitors. store and days filter both. A map holds only dates actually observed; an empty map means no measurement in range, never zero. If users_rounded_in_range is true the store published rounded counts somewhere in the window, so small movements there may be rounding. Competitors are captured every few days rather than daily, and not on a fixed schedule, so compare a rival against "listings" on dates present in both, never by position in the map. Join a competitor entry back to list_competitors on (store, external_id); name is a label, not an identifier. include_competitors adds every roster competitor's history. competitors narrows that to specific (store, external_id) pairs and implies include_competitors; a pair not on the roster fails the whole call rather than silently dropping it. Needs an ExtensionDash account. Without one, find_listing and get_store_listing still read any extension's current store page; sign up at https://extensiondash.com/signup and reconnect using the URL on your /profile page for anything else.

NameTypeReqDescription
competitorsarray–Limit competitor history to these (store, external_id) pairs from list_competitors. Implies include_competitors; an unlisted pair fails the call.
daysinteger–How far back to look. Defaults to 30.
extension_idintegeryesFrom list_extensions.
include_competitorsboolean–Also return history for this extension's promoted competitors. Defaults to false.
storestring–Filters both listings and competitors. Omit for every store.

No output schema declared.

No examples provided.

get_store_listing ~440

One extension's store page, straight from the store — any extension, tracked by this account or not. Copy comes back as readable text: AMO serves HTML, and its tags, entities and redirector URLs are stripped so a description reads as prose rather than as markup. Chrome's copy is already text and is passed through unchanged. This is the competitor-research and copy-review tool: full description, supported languages, category, install count, rating, and version, in whichever store language you ask for. Chrome listings return supported languages as the store renders them ("Deutsch", "français"); Firefox returns locale codes ("de", "fr"). That difference is real, not a bug. Reading a listing never starts tracking it. Signed in, a read of a Chrome listing already stored here -- tracked by any account, not just yours -- may add a point to its copy timeline. A guest read writes no research state, though the call itself is still logged and rate-limited like any other. Use get_extension instead for an extension this account tracks, when you want its recorded numbers over time. Cached for a day and fetched in the background: a cold call returns status "pending", so call again with the same arguments until it reads "ready". Without an account this answers from cache only: a listing nobody has fetched yet returns status "sign_in_required", and calling again will not change that.

NameTypeReqDescription
external_idstringyesChrome's 32-letter id, or the AMO slug, numeric id, or guid.
include_copy_historyboolean–Also return every recorded wording of this listing, newest first. Only listings already stored here have one -- tracked by any account, not just yours -- and only signed in; a guest read never receiv…
localestring–Store language: "en", "de", "ru". Defaults to "en".
max_ageinteger–Accept a cached answer up to this many seconds old. Defaults to a day.
storestringyes–

No output schema declared.

No examples provided.

list_competitors ~236

Who this extension competes with, measured across every keyword it tracks. Two sets. "competitors" is the roster you promoted with add_competitor: their descriptions, install counts and ratings are recorded, and their positions are kept even on days they fall out of the results. "candidates" — returned only with include_observed — is everyone else who has appeared in those searches, ranked by how often they beat you. Both are read from positions this account already recorded, not from the store: no fetch, no waiting, and each row carries the evidence behind it (how many of your terms, average position, first seen). This is the tool for deciding who is worth promoting. Needs an ExtensionDash account. Without one, find_listing and get_store_listing still read any extension's current store page; sign up at https://extensiondash.com/signup and reconnect using the URL on your /profile page for anything else.

NameTypeReqDescription
extension_idintegeryesFrom list_extensions.
include_observedboolean–Also return unpromoted candidates. Defaults to false.

No output schema declared.

No examples provided.

list_extensions ~145

Every extension this token's owner tracks, with each store listing's latest numbers: user count (and whether the store rounded it), the 7-day change, rating, ratings count and category rank. Start here when this connection has an account: every tracking tool takes an extension_id from this list. Without one, start at find_listing instead -- it needs no account and turns a name into the store id get_store_listing reads. Needs an ExtensionDash account. Without one, find_listing and get_store_listing still read any extension's current store page; sign up at https://extensiondash.com/signup and reconnect using the URL on your /profile page for anything else.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

list_keywords ~454

Every search term tracked for one extension, one row per term per store. status is "pending" until a fetch has landed since the term was tracked, and "scanned" once one has. A "scanned" row with a null position means we searched depth_scanned results and this extension was not among them — that is a real observation, not missing data. A "pending" row can still carry a position. Removing a keyword stops the tracking but keeps the history, so a term tracked before and added again arrives with its previous result already in place; captured_on says how old that is. Poll until the status reads "scanned" to know the number answers the current tracking. locale is the store language the term was searched in. The same term ranks differently under hl=de than under hl=en, so two rows sharing a term and a store are two different results. locales lists every store language this extension tracks, with a keyword count each — start there to work a language at a time. It always reports every language, including when the locale argument narrows the rows to one. search_volume is Google Ads' average monthly searches for the term, worldwide, in the row's store language. It is web search demand, not searches inside the store, and is the same for both stores. null means not fetched yet, Google has no data, or the term can't be looked up (symbols such as + or %, over 80 characters or 10 words, or a store language without a Google Ads mapping); search_volume_fetched_at says which. Needs an ExtensionDash account. Without one, find_listing and get_store_listing still read any extension's current store page; sign up at https://extensiondash.com/signup and reconnect using the URL on your /profile page for anything else.

NameTypeReqDescription
extension_idintegeryesFrom list_extensions.
localestring–Store language, e.g. "de". Omit for every language. Canonicalised before use, so "DE" and "de" are one keyword and "pt-br" comes back as "pt-BR".

No output schema declared.

No examples provided.

list_scrape_runs ~170

Recent scrape attempts against your own extensions, newest first, with their outcome and any error. Covers both the listing fetches and the rank fetches for the search terms they track. Use this after add_keyword to watch the rank fetch: the run is targeted at the search term, and a failed fetch appears here as a failure rather than as a position that never arrives. Needs an ExtensionDash account. Without one, find_listing and get_store_listing still read any extension's current store page; sign up at https://extensiondash.com/signup and reconnect using the URL on your /profile page for anything else.

remove_competitor ~146

Stop tracking a competitor for an extension. Stops the store fetches. The recorded history is kept, so adding the same competitor again later restores its charts rather than starting from zero — and its positions carry on being observed either way, because they come from searches this account already runs. Needs an ExtensionDash account. Without one, find_listing and get_store_listing still read any extension's current store page; sign up at https://extensiondash.com/signup and reconnect using the URL on your /profile page for anything else.

remove_keyword ~276

Stop tracking a search term for an extension, across every store it was tracked in. Positions already recorded are kept; only the tracking stops. Other extensions tracking the same term through their own store listings are unaffected. A store listing can itself be shared by several extensions, though — when it is, they share one tracking, and removing the term from one removes it from all of them. A term is tracked per store language. Tracking "ad blocker" in en and again in de gives two independent keywords with their own positions. Call list_keywords for the languages an extension already tracks. Needs an ExtensionDash account. Without one, find_listing and get_store_listing still read any extension's current store page; sign up at https://extensiondash.com/signup and reconnect using the URL on your /profile page for anything else.

No examples provided.

search_store ~443

Search a store the way a shopper would, and read the results. This is how you see a real SERP: who ranks for a term, in what order, with the titles and taglines they rank with. Results are not limited to extensions this account tracks — any competitor is visible — and, signed in, any result that IS one of yours carries its extension_id, so "where am I, and who is above me" is one call. locale is a real ranking axis, not a translation of the page. The same term returns a different order, and partly different extensions, under hl=de than under hl=en. Search the market you care about. Signed in, any row you already track as a competitor carries competitor_of, the ids of the extensions watching it, so you can read a page and see at a glance who is already on a roster and who is new. Results are cached for a day and fetched in the background. A cold search returns status "pending": call again with the same arguments until it reads "ready". Rows are deliberately thin — call get_store_listing for a description, supported languages, or install counts. To rank rivals rather than read one page, use list_competitors with include_observed: it scores everyone already seen across every term you track, from recorded history, with no fetch at all. Without an account this answers from cache only: a term nobody has fetched yet returns status "sign_in_required", and calling again will not change that.

NameTypeReqDescription
localestring–Store language: "en", "de", "ru". Defaults to "en". Changes the results, not just the wording.

Common questions

What is the ExtensionDash MCP server?

ExtensionDash is an MCP server listed in the public MCP registry as io.github.tonic20/extensions-dashboard. Research extension listings and search results; track installs, keyword rankings, and competitors. This page covers its hosted endpoint (https://extensiondash.com/mcp).

Is the ExtensionDash MCP server safe to use?

ExtensionDash scores 60 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the ExtensionDash MCP server expose?

ExtensionDash exposes 15 tools: list_extensions, get_extension, get_metrics_history, list_keywords, get_keyword_ranks, and 10 more. Their descriptions and schemas cost roughly 4,618 tokens of context every time the server is loaded.

Does the ExtensionDash MCP server require authentication?

No. We connected to ExtensionDash without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

Is the ExtensionDash MCP server still maintained?

ExtensionDash is still listed as active in the MCP registry. We last reached this channel on 1 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
