ims-mcp 1.0.7

Model Context Protocol server for IMS (Instruction Management Systems)

ims-mcp

Model Context Protocol (MCP) server for Rosetta (Enterprise Engineering Governance and Instructions Management System)

Powered by R2R technology for advanced RAG capabilities

This package provides a FastMCP server that connects to IMS servers for advanced retrieval-augmented generation (RAG) capabilities. It enables AI assistants like Claude Desktop, Cursor, and other MCP clients to search, retrieve, and manage documents in Rosetta knowledge bases.

Features

• 🔍 Semantic Search - Vector-based and full-text search across documents
• 🤖 RAG Queries - Retrieval-augmented generation with configurable LLM settings
• 📝 Document Management - Upload, update, list, and delete documents with upsert semantics
• 🏷️ Metadata Filtering - Advanced filtering by tags, domain, and custom metadata
• 🌐 Environment-Based Config - Zero configuration, reads from environment variables

Installation

Using uvx (recommended)

The easiest way to use ims-mcp is with uvx, which automatically handles installation:

uvx ims-mcp

Using pip

Install globally or in a virtual environment:

pip install ims-mcp

Then run:

ims-mcp

As a Python Module

You can also run it as a module:

python -m ims_mcp

Configuration

The server automatically reads configuration from environment variables:

Variable	Description	Default
R2R_API_BASE or R2R_BASE_URL	IMS server URL	http://localhost:7272
R2R_COLLECTION	Collection name for queries	Server default
R2R_API_KEY	API key for authentication	None
R2R_EMAIL	Email for authentication (requires R2R_PASSWORD)	None
R2R_PASSWORD	Password for authentication (requires R2R_EMAIL)	None

Authentication Priority:

1. If R2R_API_KEY is set, it will be used
2. If R2R_EMAIL and R2R_PASSWORD are set, they will be used to login and obtain an access token
3. If neither is set, the client will attempt unauthenticated access (works for local servers)

Note: Environment variables use R2R_ prefix for compatibility with the underlying R2R SDK.

Usage with MCP Clients

Cursor IDE

Local server (no authentication):

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "KnowledgeBase": {
      "command": "uvx",
      "args": ["ims-mcp"],
      "env": {
        "R2R_API_BASE": "http://localhost:7272",
        "R2R_COLLECTION": "aia-r1"
      }
    }
  }
}

Remote server (with email/password authentication):

{
  "mcpServers": {
    "KnowledgeBase": {
      "command": "uvx",
      "args": ["ims-mcp"],
      "env": {
        "R2R_API_BASE": "https://your-server.example.com/",
        "R2R_COLLECTION": "your-collection",
        "R2R_EMAIL": "[e-mail]",
        "R2R_PASSWORD": "your-password"
      }
    }
  }
}

Claude Desktop

Add to Claude Desktop configuration (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "ims": {
      "command": "uvx",
      "args": ["ims-mcp"],
      "env": {
        "R2R_API_BASE": "http://localhost:7272",
        "R2R_COLLECTION": "my-collection"
      }
    }
  }
}

Other MCP Clients

Any MCP client can use ims-mcp by specifying the command and environment variables:

{
  "command": "uvx",
  "args": ["ims-mcp"],
  "env": {
    "R2R_API_BASE": "http://localhost:7272"
  }
}

Available MCP Tools

1. search

Perform semantic and full-text search across documents.

Parameters:

• query (str): Search query
• filters (dict, optional): Metadata filters (e.g., {"tags": {"$in": ["agents"]}})
• limit (int, optional): Maximum results
• use_semantic_search (bool, optional): Enable vector search
• use_fulltext_search (bool, optional): Enable full-text search

Example:

search("machine learning", filters={"tags": {"$in": ["research"]}}, limit=5)

2. rag

Retrieval-augmented generation with LLM.

Parameters:

• query (str): Question to answer
• filters (dict, optional): Metadata filters
• limit (int, optional): Max search results to use
• model (str, optional): LLM model name
• temperature (float, optional): Response randomness (0-1)
• max_tokens (int, optional): Max response length

Example:

rag("What is machine learning?", model="gpt-4", temperature=0.7)

3. put_document

Upload or update a document with upsert semantics.

Parameters:

• content (str): Document text content
• title (str): Document title
• metadata (dict, optional): Custom metadata (e.g., {"tags": ["research"], "author": "John"})
• document_id (str, optional): Explicit document ID

Example:

put_document(
    content="Machine learning is...",
    title="ML Guide",
    metadata={"tags": ["research", "ml"]}
)

4. list_documents

List documents with pagination and optional tag filtering.

Parameters:

• offset (int, optional): Documents to skip (default: 0)
• limit (int, optional): Max documents (default: 100)
• document_ids (list[str], optional): Specific IDs to retrieve
• compact_view (bool, optional): Show only ID and title (default: True)
• tags (list[str], optional): Filter by tags (e.g., ["agents", "r1"])
• match_all_tags (bool, optional): If True, document must have ALL tags; if False (default), document must have ANY tag

Examples:

# List all documents (compact view - ID and title only)
list_documents(offset=0, limit=10)

# List with full details
list_documents(offset=0, limit=10, compact_view=False)

# Filter by tags (ANY mode - documents with "research" OR "ml")
list_documents(tags=["research", "ml"])

# Filter by tags (ALL mode - documents with both "research" AND "ml")
list_documents(tags=["research", "ml"], match_all_tags=True)

Note: Tag filtering is performed client-side after fetching results. For large collections with complex filtering needs, consider using the search() tool with metadata filters instead.

5. get_document

Retrieve a specific document by ID or title.

Parameters:

• document_id (str, optional): Document ID
• title (str, optional): Document title

Example:

get_document(title="ML Guide")

6. delete_document

Delete a document by ID.

Parameters:

• document_id (str, required): The unique identifier of the document to delete

Example:

delete_document(document_id="550e8400-e29b-41d4-a716-446655440000")

Returns:

• Success message with document ID on successful deletion
• Error message if document not found or permission denied

Metadata Filtering

• $eq: Equal
• $neq: Not equal
• $gt, $gte: Greater than (or equal)
• $lt, $lte: Less than (or equal)
• $in: In array
• $nin: Not in array
• $like, $ilike: Pattern matching (case-sensitive/insensitive)
