build_bomComposes a complete BOM for a reference build — quantities, dated indicative prices, per-line rationale, a compatibility verdict for the chosen set, and a CSV export.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Composes a complete BOM for a reference build — quantities, dated indicative prices, per-line rationale, a compatibility verdict for the chosen set, and a CSV export. Override any role with choices.
Annotations the server declares
- readOnlyHint: true

- idempotentHint: true
- openWorldHint: false

  annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "evaluate": a word for a change.
  What this check looks for
Description, as the server wrote it
Evaluates a part set against the build's engineering constraints — supply windows, stall vs peak current, shaft/wheel fit, interfaces, solar chain — with a reasoned verdict per check. Every number cited is a corroborated attribute.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
get_provenanceThe receipt behind a stated value: the verbatim source quote, the page, the extraction method, and the sha-256 of the exact file it was read from — plus a ready-made citation line.1 finding
Why it is in this group
- The name "get_provenance" says "get": a word for reading.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it
The receipt behind a stated value: the verbatim source quote, the page, the extraction method, and the sha-256 of the exact file it was read from — plus a ready-made citation line. Omit code for every attribute's receipt.

compare_partsAligned attribute-by-attribute comparison of two catalogue parts.No findings
Why it is in this group
- The name "compare_parts" says "compare": a word for reading.
Description, as the server wrote it
Aligned attribute-by-attribute comparison of two catalogue parts. Absence means the sources did not state a value — never that the part lacks the property.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
fetchFetch the full provenance-backed record for a search result id as a citable document.No findings
Why it is in this group
- The name "fetch" says "fetch": a word for reading.
Description, as the server wrote it
Fetch the full provenance-backed record for a search result id as a citable document. Alias of get_part shaped to the search/fetch connector contract.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false

Why it is in this group
- The name "get_part" says "get": a word for reading.
Description, as the server wrote it
The complete canonical record for one part: every attribute with its provenance (source, page, verbatim quote, file hash), vendors with dated indicative prices, and datasheet links.

Description, as the server wrote it
The catalogue's reference builds (robot, weather station, plant waterer) with their roles and candidate parts — the starting point for build_bom.
Annotations the server declares

list_categoriesEvery category in the catalogue with its part count.No findings
Why it is in this group

Every category in the catalogue with its part count.

searchSearch the Partsgraph demo catalogue.No findings
Why it is in this group
- The name "search" says "search": a word for reading.
Description, as the server wrote it
Search the Partsgraph demo catalogue. Returns result ids for fetch. Alias of search_parts shaped to the search/fetch connector contract.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
search_partsFull-text search over the demo catalogue's provenance-backed part records.No findings
Why it is in this group
- The name "search_parts" says "search": a word for reading.
Description, as the server wrote it
Full-text search over the demo catalogue's provenance-backed part records. Filter by category, build or role. Every attribute returned was corroborated against the manufacturer datasheet or vendor page.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
view_bomComposes the BOM for a reference build and renders it as an interactive view in clients that support MCP Apps.No findings
Why it is in this group
- The name "view_bom" says "view": a word for reading.
Description, as the server wrote it
Composes the BOM for a reference build and renders it as an interactive view in clients that support MCP Apps. Same data as build_bom.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as catalog. Review it before you use it.

Keep track

Get told when this server's tools change: a new tool, a new description, a new class.

Anlyon alternative

3 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
