Description, as the server wrote it: ```untrusted-server-text Delete a published Compoid record. IRREVERSIBLE. The record is tombstoned and drops out of all search results. Use it to clean up test records. Only PUBLISHED records can be deleted - drafts have no PID until they are published, so a draft must be published first (or cancelled via the review flow) before it can be addressed this way. The API token's user must be the record's creator or an owner of the record's community; otherwise the API returns 403. Required: work_id: the record to delete - a published record PID (e.g. '4171t-rc787'), a full record URL (https://www.compoid.com/records/), or its OAI. On success returns a confirmation (HTTP 204). On failure the error includes an actionable hint (403 = wrong user/permissions, 404 = not found or draft). ``` ### `Compoid_update_community` - The name "Compoid_update_community" says "update": a word for a change. - The server marks it destructive (destructiveHint: true). - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Only supply the fields you want to change. ``` ## Changes things (5) Creates or changes something that can be changed back. Claude Code: ask. ### `Compoid_create_community` - The name "Compoid_create_community" says "create": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Create a new community on Compoid. ``` ### `Compoid_create_record` - The name "Compoid_create_record" says "create": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Create a new Compoid record and submit it to a community for review. Required: file_upload: the file to attach. Accepted: (1) a data URI 'data:;base64,' (base64-encode client-side files), or (2) a path on the MCP server host such as '/projects/...' (e.g. the path returned by Compoid_upload_file). Plain client-local paths are NOT accessible to the server. creators: non-empty list of author / AI-model names (e.g. ['John Doe']); for AI-generated content include the model name as a co-creator (e.g. ['Qwen']). keywords: non-empty list of tags (e.g. ['Compoid', 'MCP']) - records without keywords are hard to discover. Recommended (thin records are hard to discover and may be rejected): title, description: a clear title and abstract. resource_type: one of analysis, image, video, audio, publication, document, software, project, dataset, presentation, workflow, tutorial, event, crypto, forex, indices, equities, physicalobject, model, other - any other value is rejected with 400 'Not a valid value.' (when omitted it is inferred from the file MIME type). subjects: up to 5 subject display names from the Compoid subject vocabulary (https://www.compoid.com/subjects); invalid names cause a 400. "Artificial Intelligence" is always appended as a default subject. Optional: community_id: community slug (e.g. 'physics' - browse https://www.compoid.com/communities or use Compoid_search_communities), a community UUID, or a home-community slug 'user-'. When omitted, the record is submitted to the API token's own home community (resolved via Compoid_whoami). ``` ### `Compoid_download_files` - Nothing in its name or description says what it does, so it is counted as a write. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Download record files in a zip archive if available through open access. ``` ### `Compoid_update_record` - The name "Compoid_update_record" says "update": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Update an existing Compoid record (creates a new version, pending review). Only pass the fields you want to change; unprovided fields keep their current values. An update with no changed fields is rejected as a no-op. Required: work_id: the record to update - a published record PID (e.g. '4171t-rc787'), a full record URL, or its OAI. Drafts have no PID until published, so only published records can be updated. Optional (any subset): file_upload: replacement file (data URI or MCP-server-host path) - only when replacing the file. title, description, creators, keywords, references: metadata to change. resource_type: must be one of analysis, image, video, audio, publication, document, software, project, dataset, presentation, workflow, tutorial, event, crypto, forex, indices, equities, physicalobject, model, other - any other value is rejected with 400 'Not a valid value.' subjects: up to 5 subject display names (https://www.compoid.com/subjects). Omit to keep the record's existing subjects; "Artificial Intelligence" is always appended as a default. ``` ### `Compoid_upload_file` - The name "Compoid_upload_file" says "upload": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Upload a file to the Compoid MCP server. Accepts a data URI (data:;base64,). Returns the server-side path to use as file_upload in Compoid_create_record or Compoid_update_record. ``` ## Only reads (7) Looks things up and changes nothing. Claude Code: allow. ### `Compoid_get_collection_records` - The name "Compoid_get_collection_records" says "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. Description, as the server wrote it: ```untrusted-server-text Get the records that belong to a specific Compoid collection. collection_id is the numeric ID from Compoid_search_collections; an optional query is AND-ed on top of the collection's own scope. ``` ### `Compoid_get_community_details` - The name "Compoid_get_community_details" says "get": a word for reading. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
