Version: 2.1.0

Documentation — Installation, deployment, usage across the API, CLI, MCP, and agent interfaces, and guidance for provisioning the DocumentDB backing service are maintained in the official documentation.


Overview

Documentdb Mcp is a production-grade Agent and Model Context Protocol (MCP) server designed to interface directly with DocumentDB MCP Server & A2A Server. DocumentDB is a MongoDB compatible open source document database built on PostgreSQL..


Key Features

  • Consolidated Action-Routed MCP Tools: Minimizes token overhead and eliminates tool bloat in LLM contexts by grouping methods into optimized, togglable tool modules.
  • Enterprise-Grade Security: Comprehensive support for Eunomia policies, OIDC token delegation, and granular execution context tracking.
  • Integrated Graph Agent: Built-in Pydantic AI agent supporting the Agent Control Protocol (ACP) and standard Web interfaces (AG-UI).
  • Native Telemetry & Tracing: Out-of-the-box OpenTelemetry exports and native Langfuse tracing.

CLI or API

This agent wraps the DocumentDB MCP Server & A2A Server. DocumentDB is a MongoDB compatible open source document database built on PostgreSQL. API. You can interact with it programmatically or via its integrated execution entrypoints.

Detailed instructions on how to use the underlying API wrappers, extended schema bindings, and developer SDK references are maintained in docs/index.md.


MCP

This server utilizes dynamic Action-Routed tools to optimize token overhead and maximize IDE compatibility.

Dynamic Tool Selection & Visibility

This MCP server supports dynamic toolset selection and visibility filtering at runtime. This allows you to restrict the set of exposed tools in order to prevent blowing up the LLM's context window.

You can configure tool filtering via multiple input channels:

  • CLI Arguments: Pass --tools or --toolsets (or their disabled counterparts --disabled-tools and --disabled-toolsets) during startup.
  • Environment Variables: Define standard environment variables:
    • MCP_ENABLED_TOOLS / MCP_DISABLED_TOOLS
    • MCP_ENABLED_TAGS / MCP_DISABLED_TAGS
  • HTTP SSE Request Headers: Pass custom headers during transport initialization:
    • x-mcp-enabled-tools / x-mcp-disabled-tools
    • x-mcp-enabled-tags / x-mcp-disabled-tags
  • HTTP SSE Request Query Parameters: Append query parameters directly to your transport connection URL:
    • ?tools=tool1,tool2
    • ?tags=tag1

When query strings or parameters are supplied, an LLM-free Knowledge Graph resolution layer (using DynamicToolOrchestrator) matches query intents against known tool tags, names, or descriptions, with safe fallback and automated 24-hour background cache refreshing.


MCP Configuration Examples

Install the connector-focused [mcp] extra. Examples use documentdb-mcp[mcp] to add FastMCP / FastAPI through agent-utilities[mcp]; the required Agent Utilities core still carries epistemic-graph[full]. The [agent-runtime] extra additionally enables model orchestration.

stdio Transport (local IDEs — Cursor, Claude Desktop, VS Code)

{
  "mcpServers": {
    "documentdb-mcp": {
      "command": "uvx",
      "args": [
        "--from",
        "documentdb-mcp[mcp]",
        "documentdb-mcp"
      ],
      "env": {
        "MCP_TOOL_MODE": "intent",
        "ANALYSISTOOL": "True",
        "COLLECTIONSTOOL": "True",

        "SYSTEMTOOL": "True",
        "USERSTOOL": "True"
      }
    }
  }
}

Runtime references require an alias-aware launcher such as GraphOS. Other launchers must omit those entries and inject the resolved values through their own runtime secret boundary.

Streamable-HTTP Transport (networked / production)

{
  "mcpServers": {
    "documentdb-mcp": {
      "command": "uvx",
      "args": [
        "--from",
        "documentdb-mcp[mcp]",
        "documentdb-mcp",
        "--transport",
        "streamable-http",
        "--port",
        "8000"
      ],
      "env": {
        "TRANSPORT": "streamable-http",
        "HOST": "127.0.0.1",
        "PORT": "8000",
        "MCP_TOOL_MODE": "intent",
        "ANALYSISTOOL": "True",
        "COLLECTIONSTOOL": "True",

        "SYSTEMTOOL": "True",
        "USERSTOOL": "True"
      }
    }
  }
}

Alternatively, connect to a pre-deployed Streamable-HTTP instance by url:

{
  "mcpServers": {
    "documentdb-mcp": {
      "url": "http://localhost:8000/documentdb-mcp/mcp"
    }
  }
}

Run a reviewed container image as a least-privilege stdio child (no listener or published port):

docker run -i --rm \
  --read-only \
  --cap-drop=ALL \
  --security-opt=no-new-privileges \
  --pids-limit=256 \
  --tmpfs /tmp:rw,noexec,nosuid,nodev,size=64m \
  -e TRANSPORT=stdio \
  -e MCP_TOOL_MODE=intent \
  -e ANALYSISTOOL=True \
  -e COLLECTIONSTOOL=True \
  -e CRUDTOOL=True \
  -e KGTOOL=True \
  -e MONGODB_HOST=localhost \
  -e MONGODB_PORT=27017 \
  -e MONGODB_URI=mongodb://localhost:27017/ \
  -e SYSTEMTOOL=True \
  -e USERSTOOL=True \
  registry.example.invalid/documentdb-mcp@sha256:<digest> documentdb-mcp

For containerized network HTTP, supply an authenticated TLS ingress (or direct server TLS), exact MCP_ALLOWED_HOSTS, and an exact trusted-proxy CIDR policy through the operator-owned deployment profile. The generator does not emit an unauthenticated non-loopback listener.

Auto-generated from the code-read env surface (MCP_TOOL_MODE + package vars) — do not edit.

Additional Deployment Options

documentdb-mcp can run as a local stdio process or container, or behind a remote network boundary. The Deployment guide carries the detailed transport contract.

  • Local container — launch a reviewed immutable image as a least-privilege stdio child with no listener or published port.
  • Remote URL — connect through an operator-supplied authenticated HTTPS ingress. Keep its URL, outbound identity references, trust profile, and exact MCP_ALLOWED_HOSTS in AgentConfig.

Agent

This repository features a fully integrated Pydantic AI Graph Agent. It communicates over the Agent Control Protocol (ACP) and interacts seamlessly with the Agent Web UI (AG-UI) and Terminal interface.

Running the Agent CLI

To start the interactive command-line agent:

# Set credentials
export MONGODB_URI="mongodb://localhost:27017/"
export MONGODB_HOST="localhost"
export MONGODB_PORT="27017"

# Run the agent server
documentdb-agent --provider openai --model-id gpt-4o

Docker Compose Orchestration

The following docker/agent.compose.yml configures the Agent, Web UI, and Terminal Interface together:

Security & Governance

Built directly upon the enterprise-ready agent-utilities core, standard security parameters are fully supported:

Access Control & Policy Enforcement

  • Eunomia Policies: Fine-grained, policy-driven tool authorization. Supports none, local embedded (mcp_policies.json), or centralized remote modes.
  • OIDC Token Delegation: Compliant with RFC 8693 token exchange for flowing authenticating user credentials from Web UI / ACP → Agent → MCP.
  • Scoped Credentials: Execution context runs restricted to the specific caller identity.

Installation

Pick the extra that matches what you want to run:

Extra Installs Use when
documentdb-mcp[mcp] Connector-focused MCP server (agent-utilities[mcp] — FastMCP/FastAPI + epistemic-graph[full]) You only run the MCP server (smallest install / image)
documentdb-mcp[agent] Agent runtime (agent-utilities[agent-runtime,logfire] — model orchestration + epistemic-graph[full]) You run the integrated agent
documentdb-mcp[all] Everything (mcp + agent + logfire) Development / both surfaces
# Connector-focused MCP server (includes the shared graph engine)
uv pip install "documentdb-mcp[mcp]"

# Agent runtime (adds model orchestration to the shared graph engine)
uv pip install "documentdb-mcp[agent]"

# Everything (development)
uv pip install "documentdb-mcp[all]"      # or: python -m pip install "documentdb-mcp[all]"

Container images (:mcp vs :agent)

One multi-stage docker/Dockerfile builds two right-sized images, selected by --target:

Image tag Build target Contents Entrypoint
example/documentdb-mcp:mcp --target mcp documentdb-mcp[mcp] — connector-focused, includes epistemic-graph[full]; no model-orchestration stack documentdb-mcp
example/documentdb-mcp@sha256:<digest> --target agent (default) documentdb-mcp[agent] — agent runtime, model orchestration + epistemic-graph[full] documentdb-agent
docker build --target mcp   -t example/documentdb-mcp:mcp    docker/   # connector-focused MCP server
docker build --target agent -t example/documentdb-mcp:agent-local docker/   # agent runtime

docker/mcp.compose.yml runs the connector-focused :mcp server; docker/agent.compose.yml runs the agent (immutable agent digest) with a co-located :mcp sidecar.

Knowledge-graph database (epistemic-graph)

Both [mcp] and [agent] carry the epistemic-graph engine through the required Agent Utilities core dependency (epistemic-graph[full]). The [mcp] extra keeps the server connector-focused; [agent] additionally enables model orchestration. Local deployments can use the bundled engine. For production or shared state, run epistemic-graph as a dedicated database service and configure the runtime to use it. Deployment recipes (single-node + Raft HA), connection configuration, and architecture diagrams are documented in the epistemic-graph deployment guide. This graph service is distinct from the DocumentDB backing store used by the MCP tools; see the connection variables above.

Deploy with agent-utilities-deployment

Provision this package with the consolidated agent-utilities-deployment workflow. It selects an installed-package, editable-source, or immutable-container path; records only runtime secret and TLS-profile references in AgentConfig; and runs doctor, registration, policy, observability, and rollback gates. Ask your agent to "deploy documentdb-mcp with agent-utilities-deployment".

Install mode Command
Installed package uv tool install "documentdb-mcp[mcp]", then run documentdb-mcp
Editable source uv pip install -e ".[agent]", then run documentdb-mcp
Immutable container deploy registry.example.invalid/documentdb-mcp@sha256:<digest> through the operator-selected orchestrator

The repository embeds no deployment profile, credential value, certificate path, or environment-specific endpoint. Supply those at runtime through AgentConfig and the configured secret provider.

Governed capability contract

This package ships a compact canonical skill surface with specialist procedures kept as referenced workflows. The current MCP tools, skill metadata, connector_manifest.yml, ontology, mappings, shapes, fixtures, migrations, tool-schema fingerprints, and certification metadata form one versioned capability contract. Validate them together; do not rely on stale tool names or historical per-task skill wrappers.

Runtime endpoints, credentials, certificate trust, tenant identity, retention, and observability policy are deployment inputs and are never packaged values. See Configuration, trust, and privacy before enabling a network transport, connector ingestion, GraphOS delegation, or trace export.
