ims-mcp 2.0.0b62

Model Context Protocol server for Rosetta (Instruction Management System)

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 Rosetta 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

• 🧭 Context Bootstrap - get_context_instructions loads bootstrap rules for agent setup
• 📚 Instruction Retrieval - query_instructions fetches docs by keyword or tags
• 🗂️ Project Context Management - discover, query, and store project datasets
• 📝 Feedback Capture - structured submit_feedback for workflow learning loops
• 🔗 Instruction Resources - rosetta://{path*} resource template for bundled reads
• 🌐 Environment-Based Config - Zero configuration, reads from environment variables
• 🔐 STDIO + HTTP OAuth - API-key runtime plus OAuth proxy support for HTTP transports
• 📊 Usage Analytics - Built-in PostHog integration for tracking feature adoption (enabled by default, opt-out)

Installation

Using uvx (recommended)

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

uvx ims-mcp@latest

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

Rosetta MCP supports two runtime modes:

1. STDIO (default) for MCP clients that launch a local process (command + args)
2. HTTP for remote/server deployment behind OAuth

  "mcpServers": {
    "RosettaHTTP": {
      "url": "https://rosetta.evergreen.gcp.griddynamics.net/mcp"
    }
  }

Development

Local Installation

Install directly from PyPI:

pip install ims-mcp

Or for the latest development version, install from source if you have the code locally:

pip install -e .

Running Tests

pip install -e ".[dev]"
pytest

Building for Distribution

python -m build

Usage Analytics

Rosetta MCP includes built-in usage analytics via PostHog to help understand feature adoption and usage patterns.

Default Behavior

Published packages (from PyPI via CI/CD): Analytics are ENABLED BY DEFAULT with a built-in Project API Key (write-only, safe for client-side use). No configuration required.

Local development builds: Analytics are DISABLED (placeholder key remains in source code).

Disable Analytics

To disable analytics, set POSTHOG_API_KEY to an empty string in your MCP configuration:

{
  "mcpServers": {
    "KnowledgeBase": {
      "command": "uvx",
      "args": ["ims-mcp@latest"],
      "env": {
        "ROSETTA_TRANSPORT": "stdio",
        "ROSETTA_SERVER_URL": "https://ims.evergreen.gcp.griddynamics.net",
        "ROSETTA_API_KEY": "your-rosetta-api-key",
        "POSTHOG_API_KEY": ""
      }
    }
  }
}

Use Custom PostHog Project

To track analytics in your own PostHog project, provide your Project API Key:

{
  "mcpServers": {
    "KnowledgeBase": {
      "env": {
        "POSTHOG_API_KEY": "phc_YOUR_CUSTOM_PROJECT_API_KEY",
        "POSTHOG_HOST": "https://us.i.posthog.com"
      }
    }
  }
}

Where to Find Your Project API Key:

1. Log into PostHog dashboard
2. Navigate to: Project Settings → Project API Key
3. Copy the key (starts with phc_)

Important: Use Project API Key (write-only, for event ingestion), not Personal API Key.

What's Tracked

User Context:

• Username (from USER/USERNAME/LOGNAME environment variables + whoami fallback)
• Repository names (from MCP roots/list protocol request, comma-separated if multiple; fallback to client_id parsing; 5-min cache)
• MCP server identifier (mcp_server: "Rosetta") and runtime package version (mcp_server_version)
• GeoIP enabled via disable_geoip=False in client initialization (MCP runs locally on user's machine, IP is user's actual location)

Business Parameters (usage patterns):

• Tool arguments such as query, tags, repository_name, request_mode, document, and force

Excluded (technical parameters):

• limit, offset, page - Pagination
• compact_view - View settings
• model, temperature, max_tokens - RAG tuning parameters

Privacy & Control

• Opt-out: Analytics enabled by default with built-in key, easy to disable
• Write-only: Project API key can only send events, cannot read analytics data
• Non-blocking: Analytics never delays or breaks MCP tool responses
• User control: Set POSTHOG_API_KEY="" to disable tracking anytime
• Custom tracking: Use your own PostHog project by setting custom API key

Requirements

• Python >= 3.10
• Rosetta Server running and accessible
• ragflow-sdk >= 0.24.0
• mcp >= 1.26.0
• posthog >= 7.0.0 (for built-in analytics)
