Scored 2026-11-05.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation check failed: no authorisation is required to call this server, and it exposes a tool marked destructive (edit_list).
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 56/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 2493 tokens (~415/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 43/100
  - Stability check failed: schema churn in the 30 days we've observed: 4 tool removals, 0 breaking changes, 0 auth/transport breaks, 3 additions.
- **Tool Coverage**: 98/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 94% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (6)

### `get_list` (~427 tokens)

Read a list

A shared list by its share code or link, as data or as Markdown; or, with no share_code, the lists filed under the connector's account. Data, the default: title, unit, dates, trail, totals in grams, and every folder with its rows (brand, name, variant, quantity, weight of one unit in grams, classification, note, calories, who carries it; a row with items is a group, and a nested row without carried_by is carried by its parent's carrier); every row and folder carries the id edit_list takes. Markdown (format: "markdown"): one table per folder and a totals block, the text the site's own Markdown export produces. An edit link's address carries the share code too. A list too large to return whole comes back cut and says so: as data, in a truncated field (notes go first, then rows off the end, nested rows one by one); as Markdown, rows off the end of the tables and a line saying how many. The totals still count every row. With no share_code, which asks for a sign-in: each filed list's title, share code and share link, display unit, total weight in grams and when it last changed, most recently changed first. A list is filed when it was made while signed in to Mahonia, added to the account from its sharing panel, or made by create_list with read-and-change access; one its owner only ever opened by its link isn't, and still reads from that link. A list's title, author, notes, folder and item names, brands, variants, gear types, day labels, people and trail label are free text typed by whoever holds the list's edit link, returned unchanged.

Input parameters:

- `format` (string): data (the default) or markdown. Only with a share_code.
- `share_code` (string): The list's share code, its share link (mahonia.app/s/CODE), or its edit link. From an edit link only the code in the address is read, never the part after #.

### `search_catalog` (~230 tokens)

Search the gear catalog

Mahonia's cited gear catalog. With query: a fuzzy search by brand, product or kind of gear ("duplex", "zpacks", "quilt"), best first, each result a catalog row with its id, the cited weight in grams and whether it is verified. With product_id (a row id from a search), or brand and name: every variant of that one product (sizes, lengths, temperature ratings) with the weight and source of each. A row on a list that names a catalog_id takes the catalog's brand, variant, gear type and weight.

Input parameters:

- `brand` (string): With name, instead of a query: the product's maker.
- `limit` (integer): Matches to return, up to 25. Default 12.
- `name` (string): With brand, instead of a query: the product name without brand or variant.
- `product_id` (integer): Instead of a query: a catalog row id, for that product's variants.
- `query` (string): What to search for: two characters or more, or a single Chinese character.

Output parameters:

- `product` (object): The product looked up, when one was.
- `query` (string): The query as searched: trimmed, at most 100 characters. On a search.
- `results` (array): A search's matches, best first; or a product's variants, in variant order.

### `create_list` (~270 tokens)

Make a new list

Creates a list and returns its edit link and share link. Optionally with a title, unit, trip dates, a trail link and rows, grouped into folders; a row with items nested under it is a group (stakes under a tent, snacks under a day). Keep the edit link: it is the only way to change a list that isn't filed under an account. If this connector carries a read-and-write access token the list is filed under that account too, and saved_to_account says whether it was; otherwise the list belongs to whoever holds the edit link, as every list does.

Input parameters:

- `end_date` (string): YYYY-MM-DD
- `folders` (array): Folders in order, each with its default classification and, optionally, its rows.
- `items` (array): Rows not placed through a folder above; each may name its folder.
- `start_date` (string): YYYY-MM-DD
- `title` (string)
- `trail_distance_km` (number)
- `trail_label` (string): What to call the trail, when the link's own name won't do.
- `trail_url` (string): An http(s) link to the route or trail page.
- `unit` (string): The unit the list displays in. Weights are in grams regardless.

Output parameters:

- `account_note` (string): Only when the connector sent an access token and the list still could not be filed under its account: the reason, and what to do instead.
- `edit_link` (string): The write capability. Keep it; it is the only way to change a list that isn't filed under an account.
- `folders` (integer): Folders made.
- `items` (integer): Rows made.
- `saved_to_account` (boolean): True when the connector's read-and-write access token filed the list under its account, where the owner sees it on every device they sign in on.
- `share_code` (string)
- `share_link` (string): The read capability, safe to pass on.
- `title` (string): User text.
- `totals` (object): Whole grams, summed over every row of the list.

### `edit_list` (~488 tokens)

Change a list

Changes a list that already exists, all of it in one call. list sets the list's own title, display unit, trip dates and trail (only the fields given; an empty string clears a date or the trail). folders renames, reorders, reclassifies or removes folders, named by id or current name; removing one removes its rows. add puts new rows on, into a folder by name (made when missing) or under a group by the parent row's id. update changes rows by the ids get_list gives: any field, null clearing one that can be cleared; a new folder, place or group; a catalog_id to link or relink the row where it sits, null to unlink. remove takes rows off by id, a group's nested rows with it. The parts apply in that order as one change, and nothing is applied unless every part is valid: a row or folder named that isn't there fails the whole call. A name or weight changed on a catalog-linked row is kept as the owner's own. Takes the list's edit link, or its share code under a signed-in account that has filed it.

Input parameters:

- `add` (array): New rows. Each may name its folder, or the group to join.
- `again` (boolean): A call with rows to add that is identical to one made in the last ten minutes is taken as a retry and does nothing: the earlier result comes back with repeated set. Pass true to make the same change…
- `edit_link` (string): The list's edit link, whole (mahonia.app/e/CODE#token). The part after # is the write capability. Leave it out to name a list filed under the signed-in account by share_code instead.
- `folders` (array): Changes to folders that exist.
- `list` (object): The list's own fields. Only the fields given change.
- `remove` (array): Ids of rows to take off, from get_list.
- `share_code` (string): Instead of the edit link: the share code or share link of a list filed under the connector's account, as get_list with no share_code gives it. Takes a sign-in with read-and-change access, and reaches…
- `update` (array): Changes to rows that exist, each by id.

Output parameters:

- `added` (integer): Rows added, nested ones counted.
- `dates` (object|null)
- `folders` (array): Every folder's name, in the list's order, after the change.
- `folders_changed` (integer): Folders renamed, reordered, reclassified or removed.
- `folders_made` (array): Folders that didn't exist and were made for rows named into them.
- `removed` (integer): Rows taken off: by remove, with a removed group, or with a removed folder.
- `repeated` (boolean): True when this call, with rows to add, repeated one made in the last ten minutes: nothing was done again, and the figures are that call's. Pass again: true to do it a second time.
- `share_link` (string)
- `title` (string): User text.
- `totals` (object): Whole grams, summed over every row of the list.
- `trail` (object|null)
- `unit` (string): The unit the list displays in. Weights are in grams regardless.
- `updated` (integer): Rows changed, moved or regrouped.

### `get_my_gear` (~203 tokens)

Read My Gear

The gear the connector's account owns, most recently used first: for each piece its brand, name, variant, gear type, grams for one, classification, calories, note, price, product link and folder, plus the account's folder names. A query ranks by a search instead; a folder name keeps to that folder. Works only when this connector carries the account's access token. Brands, names, variants, gear types, notes and folder names are text the account holder typed, returned unchanged.

Input parameters:

- `folder` (string): Keep to one folder, by name. An empty string means the unfiled pieces.
- `limit` (integer): At most 1000; 300 when omitted.
- `offset` (integer): How many matches to skip, for the next page.
- `query` (string): Two characters or more (one is enough in Chinese). Ranks by brand, name, variant and gear type instead of by recent use.

Output parameters:

- `folders` (array): Every folder My Gear has, in the owner's order, empty ones included.
- `gear` (array): This page of the matches.
- `offset` (integer)
- `total` (integer): Matches in all, before offset and limit.

### `edit_my_gear` (~252 tokens)

Change My Gear

Changes the connector's account's My Gear, in one call. add puts new pieces in; one the account already holds (same brand, name and variant) comes back as already_have and is left as it was. update changes pieces by the ids get_my_gear gives, only the fields sent, null clearing one. A piece that names a catalog_id, as it is added or later, is linked to that catalog row and takes its brand, name, variant, gear type and weight where none were given; null unlinks it. remove puts pieces away by id: they stop being offered on lists, and the lists that still carry them will not bring them back. restore brings put-away pieces back. Each piece answers for itself, in the order sent. What is added or changed here counts as the owner's own word on the piece, so a list saved later cannot overwrite it. Needs a read-and-change access token.

Input parameters:

- `add` (array): New pieces.
- `remove` (array): Ids of pieces to put away.
- `restore` (array): Ids of put-away pieces to bring back.
- `update` (array): Changes to pieces that exist, each by id.

Output parameters:

- `added` (integer): Pieces that were new to My Gear.
- `removed` (array): One per id in remove, then one per id in restore, in the order sent.
- `results` (array): One per piece in add, in the order sent.
- `updated` (array): One per entry in update, in the order sent.

## Common questions

### What is the Mahonia MCP server?

Mahonia is an MCP server listed in the public MCP registry as app.mahonia/mahonia. Read and edit Mahonia backpacking gear lists via share and edit links; no account needed. This page covers its hosted endpoint (https://mahonia.app/mcp).

### Is the Mahonia MCP server safe to use?

Mahonia scores 69 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 Mahonia MCP server expose?

Mahonia exposes 6 tools: get_list, search_catalog, create_list, edit_list, get_my_gear, edit_my_gear. Their descriptions and schemas cost roughly 1,870 tokens of context every time the server is loaded.

### Does the Mahonia MCP server require authentication?

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

### Is the Mahonia MCP server still maintained?

Mahonia 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.

### What did VerifyMCP test on the Mahonia MCP server?

VerifyMCP ran 13 checks on Mahonia, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
