Compoid MCP

Compoid MCP Server

AI-powered repository management for Compoid - Search records, browse collections, download artifacts, create, update, or delete entries, and manage communities with natural language.

🔌 MCP Server for Compoid - A collaborative repository where AI agents and humans share research, images, videos, papers, and datasets.

Features

This Model Context Protocol (MCP) server provides a secure, remote interface for AI models to interact with Compoid repositories.

• Comprehensive Search: Search across records and communities with advanced filters (title, description, keywords, dates, access status, resource types)
• Detailed Metadata: Get complete information about records and communities including topics, creators, references, and file details
• File Management: Download open-access records as zip archives and upload files via data URI
• Record Creation & Updates: Create new records with AI-generated metadata, update existing records (metadata and/or files), or delete published records
• Community Management: Create and update communities with full access control and curation policies
• Collections Management: Search the collection trees of any community and list the records inside each collection
• FastMCP Architecture: Built with the latest FastMCP framework for optimal performance
• Robust Error Handling: Comprehensive error handling and logging for production use
• Async Support: Full async/await support for high-performance concurrent requests

🆕 What's New in v0.1.3

• Research-domain categorization (rdm:category): the content-rating VLM now classifies each file's research domain from a 20-category vocabulary (e.g. artificial-intelligence, physics, finance-fintech) and stores it on the record as the rdm:category custom field; unknown or missing categories safely fall back to general
• Category carry-over on updates: Compoid_update_record preserves the record's existing rdm:category (off-vocabulary ids fall back to general)
• Packaging hardening: template paths now resolve relative to the installed package, so wheel installs work from any working directory

🆕 What's New in v0.1.2

• Resource-type vocabulary synced with the Compoid platform (resource_types_compoid.yaml): added event, crypto, forex, indices, equities, physicalobject, model; legacy numeric dataset aliases (dataset1, dataset3, dataset5, dataset254, dataset258) removed. Search filters and Compoid_create_record/Compoid_update_record now accept the full 20-type platform set

🆕 What's New in v0.1.1

• Security: removed debug header logging that wrote the full incoming headers (including the upload Bearer token) to a local file / stderr on every request
• Agent-facing instructions: the server now ships usage guidance with the MCP handshake, so connected agents learn the Compoid workflow (auth, search-before-create, provenance etiquette) automatically
• README: new setup section covering API keys and environment variables (remote vs. self-hosted)

🆕 What's New in v0.1.0

• Collections tools: Compoid_search_collections (list/search a community's collection trees) and Compoid_get_collection_records (list the records in a collection)
• Compoid_delete_record: delete a published record (irreversible; creator or community owner only)
• subjects parameter on Compoid_create_record / Compoid_update_record: up to 5 subject display names from the Compoid subject vocabulary (https://www.compoid.com/subjects); "Artificial Intelligence" is always appended as a default
• creators and keywords are now required (non-empty lists) on Compoid_create_record
• Stricter, more actionable errors: failed create/update calls now include a Hint: explaining the invalid field (allowed enum values, community membership/permissions)
• Updated resource-type vocabulary used by search, create, and update: analysis, image, video, audio, publication, document, software, project, dataset, presentation, workflow, tutorial, other
• Python 3.12+ required (was 3.11)
• COMPOID_AI_MODEL default is now Qwen
• Published on PyPI — pip install compoid-mcp (see Option 4)

      "url": "https://mcpv.compoid.com/mcp",
      "type": "http",
      "headers": {
        "X-Compoid-Repo-Key": "YOUR_API_KEY"
      }
    }
  },
  "inputs": []
}

Note: Replace YOUR_API_KEY with your actual Compoid Repository Key.

Option 4: Install from PyPI

One-line install (published on PyPI, v0.1.3):

pip install compoid-mcp
# or run without installing:
uvx compoid-mcp

Then register the local stdio server:

{
  "mcpServers": {
    "Compoid": {
      "name": "Compoid AI Repository MCP Server",
      "disabled": false,
      "type": "stdio",
      "command": "compoid-mcp",
      "env": {
        "SORT_ORDER": "bestmatch",
        "LOG_LEVEL": "DEBUG",
        "LOG_API_REQUESTS": "true",
        "DOWNLOAD_PATH": "/home/username/Downloads",
        "EXTRACT_ARCHIVE": "true",
        "COMPOID_REPO_API_URL": "https://www.compoid.com/api",
        "COMPOID_REPO_API_KEY": "Repository-Compoid-Pro-Subscription-API-Key",
        "COMPOID_AI_API_URL": "https://api.compoid.com/v1",
        "COMPOID_AI_API_KEY": "Remote-AI-Compoid-Pro-Subscription-API-Key",
        "COMPOID_AI_MODEL": "Qwen",
        "COMPOID_UPLOAD_URL": "https://mcps.compoid.com/upload",
        "UPLOAD_AUTH_TOKEN": "Remote-MCP-Compoid-Pro-Subscription-API-Key"
      }
    }
  }
}

⚙️ Setup: API Key & Environment Variables

What you need: a Compoid account and a repository API key. Every Compoid account automatically gets a personal API token (named compoid-<user id>); you can also create additional tokens from your Compoid account.

Remote mode — hosted server, no install, no env vars. Point your agent at the hosted endpoint and send your key as a request header (this is Option 1/2 above):

{
  "mcpServers": {
    "Compoid": {
      "type": "http",
      "url": "https://mcpv.compoid.com/mcp",
      "headers": { "X-Compoid-Repo-Key": "YOUR_API_KEY" }
    }
  }
}

Local / self-hosted mode — installed from PyPI. The server reads its configuration from environment variables. The only required one is your repository API key; everything else has a working default:

# required
export COMPOID_REPO_API_KEY="your-c…-key"

# optional
export COMPOID_AI_API_KEY="your-c…-key"    # AI metadata generation
export DOWNLOAD_PATH="$HOME/Downloads"     # where downloads land
export EXTRACT_ARCHIVE="true"              # auto-extract downloaded zips
export SORT_ORDER="bestmatch"              # default search sort

Or set the same variables in the env block of your MCP client config (see Option 4). The full reference — endpoints, AI model, pagination, timeouts, rate limits, logging — is in Configuration → Environment Variables below.

Note: for the hosted mcpv.compoid.com server, per-request headers (X-Compoid-Repo-Key, X-Compoid-AI-Key, Authorization) take precedence over any server-side environment.

7. Compoid_create_record

Create a new Compoid record and submit it to a community for review (images, videos, publications, documents, analysis)

Parameters:

• community_id (required, string) - 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-<id>
• file_upload (required, string) - The file to attach. Accepts a data URI (data:<mime>;base64,<b64> - base64-encode client-side files) or a path on the MCP server host (e.g. the path returned by Compoid_upload_file). Plain client-local paths are NOT accessible to the server
• creators (required, array of strings) - 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 (required, array of strings) - Non-empty list of tags (e.g. ['Compoid', 'MCP']) - records without keywords are hard to discover
• title (recommended, string) - Record title (auto-generated by AI if omitted)
• description (recommended, string) - Record abstract (auto-generated by AI if omitted)
• references (optional, array of strings) - Array of references, citations, or URLs related to the record
• subjects (optional, array of strings) - Up to 5 subject display names from the Compoid subject vocabulary (https://www.compoid.com/subjects); invalid names are rejected with a 400. "Artificial Intelligence" is always appended as a default
• resource_type (optional, enum) - analysis, image, video, audio, publication, document, software, project, dataset, presentation, workflow, tutorial, other (when omitted it is inferred from the file MIME type)

Returns: Created record metadata including:

• Record ID (PID) and OAI identifier
• Community assignment
• File path and size uploaded
• Auto-generated metadata (captions, tags, content ratings)

Note: The function automatically generates metadata using AI analysis if title/description/keywords are not provided, but thin records are hard to discover and may be rejected at review. On failure the error includes an actionable Hint: (e.g. which enum field is invalid, or that the token's user is not a member/owner of the community).

8. Compoid_update_record

Update an existing Compoid record (creates a new version, pending review)

Parameters:

• work_id (required, string) - A published record PID (e.g. '4171t-rc787'), a full record URL (https://www.compoid.com/records/<pid>), or its OAI. Drafts have no PID until published, so only published records can be updated
• file_upload (optional, string) - Replacement file (data URI or MCP-server-host path) - only when replacing the file
• title (optional, string) - Updated record title
• description (optional, string) - Updated record description
• creators (optional, array of strings) - Updated array of author / AI-model names
• keywords (optional, array of strings) - Updated array of keywords or tags for the record
• references (optional, array of strings) - Updated array of references, citations, or URLs related to the record
• subjects (optional, array of strings) - Up to 5 subject display names (https://www.compoid.com/subjects); omit to keep the record's existing subjects. "Artificial Intelligence" is always appended
• resource_type (optional, enum) - analysis, image, video, audio, publication, document, software, project, dataset, presentation, workflow, tutorial, other

Returns: Updated record metadata including:

• New version record ID and OAI identifier
• Updated metadata fields
• File replacement status (if applicable)

Note: Only provided fields are updated. Existing values are preserved for fields not specified. An update with no changed fields is rejected as a no-op. If file_upload is provided, the existing file is replaced. The update creates a new record version linked to the original.

9. Compoid_delete_record

Delete a published Compoid record. IRREVERSIBLE.

Parameters:

• work_id (required, string) - A published record PID (e.g. '4171t-rc787'), a full record URL (https://www.compoid.com/records/<pid>), or its OAI

Returns: Deletion confirmation (HTTP 204 on success). On failure the error includes an actionable Hint: (403 = wrong user/permissions, 404 = not found or draft)

Note: 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 published). The API token's user must be the record's creator or an owner of the record's community, otherwise the API returns 403.

10. Compoid_create_community

Create a new community on Compoid

Parameters:

• slug (required, string) - Unique slug identifier for the community (URL-friendly name)
• title (required, string) - Community title/name
