MCP tools · 73 exposed · ~7,530 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
get_repricer_stats ~69

Repricer dashboard summary: total/active SKU counts, per-status breakdown, Buy Box wins and win %, items matching the Buy Box exactly, units actively repricing and the last update time. Call first for broad questions like 'how's the repricer doing?'.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

get_restock_suggestions ~113

What the user should reorder now. Per-SKU sales velocity vs stock on hand -> days of cover left, a suggested reorder quantity and its potential profit. Call for 'what should I restock?' or 'what's running low?'. lead_time_days = how long a resupply takes to land; cover_days = days of stock the reorder should provide. Requires a connected Amazon account.

No output schema declared.

No examples provided.

get_reverse_source_status ~62

get_store_results ~107

Products found by the user's storefront monitors (tracking other sellers' Amazon storefronts), newest first. Call when the user asks what their storefront monitors have found; optionally filter to one store_id. Paginated — 'total' in the response is the full count, request further pages for more. per_page max 200 (keep small: rows are wide).

get_ungate_brands ~158

The curated Sorsa ungate brand list (~1300 brands), each with a representative ASIN that can be run through request_ungate_check. Use this to look up the ASIN for a brand the user names (e.g. "can you ungate me for Adidas?" -> find Adidas here -> request_ungate_check([that asin])), or to enumerate/batch brands. Pass `search` to filter by brand substring. Returns {count, brands:[{brand, asin}]}. `count` is the full list size even when `search`/`limit` narrows the returned rows.

get_ungate_status ~176

Status + outcome of an ungate job. Status is queued | in_progress | completed | failed | expired; outcome (when set) is approved, already_approved, documents_required, not_accepting_applications, login_required or unknown. While status is 'queued' or 'in_progress', CALL THIS AGAIN after a short wait (e.g. 20-40s) — the job is processed by the user's extension serially. For 'documents_required' the response also includes Amazon's requirements text, a `suppliers` list for the brand/category, and `suggested_asins` (easier wins in the same brand). For 'login_required', tell the user to log into Seller Central and retry.

NameTypeReqDescription
checkedboolean––
notification_idintegeryes–

No output schema declared.

No examples provided.

queue_checkout ~299

Queue an Amazon checkout on the user's own desktop Chrome (requires the Sorsa extension installed and signed in there). Call when the user says e.g. 'buy 3 of this' or 'replen this ASIN at up to £20'. mode 'review' (default) drives to Amazon's review page and STOPS — the user clicks Place Order themselves. mode 'auto' places the order, but only if the user has enabled Auto checkout in the extension popup AND the order total is within max_price × qty (max_price is required for auto). max_price is ALWAYS in GBP (£) per unit, whatever the marketplace — the server converts it to the local currency at the current rate, so '£20 max on amazon.de' just works. pace 'calm' (default) clicks at a relaxed human pace — use 'fast' only for time-sensitive deals. domain is the marketplace: GB, US, DE, FR, ES or IT. The job expires after 15 minutes if the user's desktop isn't online to claim it. Always tell the user what was queued and that their desktop Chrome will open it.

request_ungate_check ~274

Request an ungate check for one or more gated ASINs. For each ASIN this confirms it's gated (via the eligibility check) and, if so, QUEUES a job that the user's Sorsa browser extension works through — it opens the Seller Central approval request in their own logged-in session and reports the outcome. Returns per-ASIN results, each one of: 'not_gated', 'already_approved', 'checking' (eligibility still resolving — re-call shortly), 'recent_attempt', 'queue_full', or 'queued' with a `job_id` (and the brand's auto-approval rate when known). Jobs run STRICTLY ONE AT A TIME, ~daily-capped, and carry over across days — so a long list is fine; it just drains serially. The user needs their Amazon (SP-API) connected AND the Sorsa extension installed and online. After queuing, poll get_ungate_status(job_id) after a short wait (jobs are processed serially, each can take tens of seconds to a few minutes). Tell the user if their extension is offline (the response includes `extension_online`).

run_sheet_action ~172

Trigger a function on the user's OWN connected Google Sheet by POSTing to their deployed Apps Script web app. Call get_sheet_status first; if not connected, tell them to connect their sheet in Sorsa Settings. `action` is the name their script's doPost dispatches on (e.g. 'send_invoice', 'add_row'). `params` is a dict of values that action needs. The user's email is always sent automatically, so the script can target the right row/recipient. Only do what the user asked — don't invent actions or params. If you're not sure which action name or params the user's script expects, ASK them rather than guessing. Returns whatever the script returns.

start_a2a_finder_scan ~157

Start an A2A Finder scan: check a list of ASINs for profitable Amazon-to-Amazon flips across marketplaces (buy on one Amazon country, sell on another). Up to 100 ASINs. Optional `countries` = list of country codes to compare (e.g. ["UK","DE","FR"]); defaults to all. Uses the user's saved Keepa key if they've added one in settings; otherwise the shared scan key (which counts against their daily scan credits). Returns a job_id — poll get_a2a_finder_status(job_id) for results. Premium feature.

start_reverse_source_scan ~115

Start a Reverse Source scan: for each ASIN, search Google Shopping for a cheaper source than Amazon — i.e. where to buy the product to flip it. Up to 250 ASINs. Uses the user's saved Keepa key if they've added one in settings; otherwise the shared scan key (which counts against their daily scan credits). Returns a job_id — poll get_reverse_source_status(job_id) for results. Premium feature.

start_wholesale_scan ~109

Matches each product to Amazon and returns profit/ROI. Returns a job_id — poll get_wholesale_status(job_id) for results. Premium feature.

Install

How do I install the Sorsa MCP server?

Sorsa is a hosted endpoint at https://sorsa.app/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.

Common questions

What is the Sorsa MCP server?

Sorsa is an MCP server listed in the public MCP registry as app.sorsa/sorsa. Amazon FBA arbitrage toolkit: product analysis, deal feeds, price alerts and sourcing management. This page covers its hosted endpoint (https://sorsa.app/mcp).

Is the Sorsa MCP server safe to use?

Sorsa scores 70 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 Sorsa MCP server expose?

Sorsa exposes 73 tools: analyse_product, analyse_product_full, get_product_sellers, get_international_prices, calculate_profit, and 68 more. Their descriptions and schemas cost roughly 7,530 tokens of context every time the server is loaded.

Does the Sorsa MCP server require authentication?

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

Is the Sorsa MCP server still maintained?

Sorsa is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
