IBM/mcp-context-forge: A Model Context Protocol (MCP) Gateway & Registry. Serves as a central management point for tools, resources, and prompts that can be accessed by MCP-compatible LLM applications. Converts REST API endpoints to MCP, composes virtual MCP servers with added security and observability, and converts between protocols (stdio, SSE, Streamable HTTP).

Model Context Protocol gateway & proxy - unify REST, MCP, and A2A with federation, virtual servers, retries, security, and an optional admin UI.

ContextForge MCP Gateway is a feature-rich gateway, proxy and MCP Registry that federates MCP and REST services - unifying discovery, auth, rate-limiting, observability, virtual servers, multi-transport protocols, and an optional Admin UI into one clean endpoint for your AI clients. It runs as a fully compliant MCP server, deployable via PyPI or Docker, and scales to multi-cluster environments on Kubernetes with Redis-backed federation and caching.

ContextForge MCP Gateway is a production-grade gateway, registry, and proxy that sits in front of any Model Context Protocol (MCP) server or REST API-exposing a unified endpoint for all your AI clients.

It supports:

• Federation across multiple MCP and REST services
• Virtualization of legacy APIs as MCP-compliant tools and servers
• Transport over HTTP, JSON-RPC, WebSocket, SSE, stdio and streamable-HTTP
• An Admin UI for real-time management and configuration
• Built-in auth, observability, retries, and rate-limiting
• Scalable deployments via Docker or PyPI, Redis-backed caching, and multi-cluster federation

For a list of upcoming features, check out the ContextForge MCP Gateway Roadmap

• Sits in front of any MCP server or REST API
• Lets you choose your MCP protocol version (e.g., 2025-03-26)
• Exposes a single, unified interface for diverse backends

• Auto-discovers or configures peer gateways (via mDNS or manual)
• Performs health checks and merges remote registries transparently
• Supports Redis-backed syncing and fail-over

• Wraps non-MCP services as virtual MCP servers
• Registers tools, prompts, and resources with minimal configuration

• Adapts REST APIs into tools with:

  • Automatic JSON Schema extraction
  • Support for headers, tokens, and custom auth
  • Retry, timeout, and rate-limit policies

• Prompts: Jinja2 templates, multimodal support, rollback/versioning
• Resources: URI-based access, MIME detection, caching, SSE updates
• Tools: Native or adapted, with input validation and concurrency controls

• Admin UI built with HTMX + Alpine.js
• Auth: Basic, JWT, or custom schemes
• Structured logs, health endpoints, metrics
• 400+ tests, Makefile targets, live reload, pre-commit hooks

MCP Gateway is published on PyPI as mcp-contextforge-gateway.

• Python ≥ 3.10 (3.11 recommended)
• curl + jq - only for the last smoke-test step

     http://127.0.0.1:4444/version | jq

Copy .env.example to .env and tweak any of the settings (or use them as env variables).

# 1️⃣  Spin up the sample GO MCP time server using mcpgateway.translate & docker
python3 -m mcpgateway.translate \
     --stdio "docker run --rm -i -p 8888:8080 ghcr.io/ibm/fast-time-server:latest -transport=stdio" \
     --port 8003

# Or using the official mcp-server-git using uvx:
pip install uv # to install uvx, if not already installed
python3 -m mcpgateway.translate --stdio "uvx mcp-server-git" --port 9000

# Alternative: running the local binary
# cd mcp-servers/go/fast-time-server; make build
# python3 -m mcpgateway.translate --stdio "./dist/fast-time-server -transport=stdio" --port 8002

# 2️⃣  Register it with the gateway
curl -s -X POST -H "Authorization: Bearer $MCPGATEWAY_BEARER_TOKEN" \
     -H "Content-Type: application/json" \
     -d '{"name":"fast_time","url":"http://localhost:9000/sse"}' \
     http://localhost:4444/gateways

# 3️⃣  Verify tool catalog
curl -s -H "Authorization: Bearer $MCPGATEWAY_BEARER_TOKEN" http://localhost:4444/tools | jq

# 4️⃣  Create a *virtual server* bundling those tools. Use the ID of tools from the tool catalog (Step #3) and pass them in the associatedTools list.
curl -s -X POST -H "Authorization: Bearer $MCPGATEWAY_BEARER_TOKEN" \
     -H "Content-Type: application/json" \
     -d '{"name":"time_server","description":"Fast time tools","associatedTools":[<ID_OF_TOOLS>]}' \
     http://localhost:4444/servers | jq

# Example curl
curl -s -X POST -H "Authorization: Bearer $MCPGATEWAY_BEARER_TOKEN"
     -H "Content-Type: application/json"
     -d '{"name":"time_server","description":"Fast time tools","associatedTools":["6018ca46d32a4ac6b4c054c13a1726a2"]}' \
     http://localhost:4444/servers | jq

# 5️⃣  List servers (should now include the UUID of the newly created virtual server)
curl -s -H "Authorization: Bearer $MCPGATEWAY_BEARER_TOKEN" http://localhost:4444/servers | jq

# 6️⃣  Client SSE endpoint. Inspect it interactively with the MCP Inspector CLI (or use any MCP client)
npx -y @modelcontextprotocol/inspector
# Transport Type: SSE, URL: http://localhost:4444/servers/UUID_OF_SERVER_1/sse,  Header Name: "Authorization", Bearer Token

export MCP_AUTH_TOKEN=$MCPGATEWAY_BEARER_TOKEN
export MCP_SERVER_CATALOG_URLS=http://localhost:4444/servers/UUID_OF_SERVER_1
python3 -m mcpgateway.wrapper  # Ctrl-C to exit

You can also run it with uv or inside Docker/Podman - see the Containers section above.

In MCP Inspector, define MCP_AUTH_TOKEN and MCP_SERVER_CATALOG_URLS env variables, and select python3 as the Command, and -m mcpgateway.wrapper as Arguments.

echo $PWD/.venv/bin/python3 # Using the Python3 full path ensures you have a working venv
export MCP_SERVER_CATALOG_URLS='http://localhost:4444/servers/UUID_OF_SERVER_1'
export MCP_AUTH_TOKEN=${MCPGATEWAY_BEARER_TOKEN}
npx -y @modelcontextprotocol/inspector

When using a MCP Client such as Claude with stdio:

{
  "mcpServers": {
    "mcpgateway-wrapper": {
      "command": "python",
      "args": ["-m", "mcpgateway.wrapper"],
      "env": {
        "MCP_AUTH_TOKEN": "your-token-here",
        "MCP_SERVER_CATALOG_URLS": "http://localhost:4444/servers/UUID_OF_SERVER_1",
        "MCP_TOOL_CALL_TIMEOUT": "120"
      }
    }
  }
}

Use the official OCI image from GHCR with Docker or Podman.

docker run --rm -it ghcr.io/ibm/mcp-context-forge:0.3.1 \
  python3 -m mcpgateway.utils.create_jwt_token --username admin --exp 0 --secret my-test-key

Browse to http://localhost:4444/admin (user admin / pass changeme).

mkdir -p $(pwd)/data

touch $(pwd)/data/mcp.db

sudo chown -R :docker $(pwd)/data

chmod 777 $(pwd)/data

• .env files - Put all the -e FOO= lines into a file and replace them with --env-file .env. See the provided .env.example for reference.

• Pinned tags - Use an explicit version (e.g. v0.3.1) instead of latest for reproducible builds.

• JWT tokens - Generate one in the running container:

  docker exec mcpgateway python3 -m mcpgateway.utils.create_jwt_token -u admin -e 10080 --secret my-test-key

• Upgrades - Stop, remove, and rerun with the same -v $(pwd)/data:/data mount; your DB and config stay intact.

curl -s -H "Authorization: Bearer $MCPGATEWAY_BEARER_TOKEN" \
     http://localhost:4444/health | jq
curl -s -H "Authorization: Bearer $MCPGATEWAY_BEARER_TOKEN" \
     http://localhost:4444/tools | jq
curl -s -H "Authorization: Bearer $MCPGATEWAY_BEARER_TOKEN" \
     http://localhost:4444/version | jq

The mcpgateway.wrapper lets you connect to the gateway over stdio while keeping JWT authentication. You should run this from the MCP Client. The example below is just for testing.

# Set environment variables
export MCPGATEWAY_BEARER_TOKEN=$(python3 -m mcpgateway.utils.create_jwt_token --username admin --exp 10080 --secret my-test-key)
export MCP_AUTH_TOKEN=${MCPGATEWAY_BEARER_TOKEN}
export MCP_SERVER_CATALOG_URLS='http://localhost:4444/servers/UUID_OF_SERVER_1'
export MCP_TOOL_CALL_TIMEOUT=120
export MCP_WRAPPER_LOG_LEVEL=DEBUG  # or OFF to disable logging

docker run --rm -i \
  -e MCP_AUTH_TOKEN=$MCPGATEWAY_BEARER_TOKEN \
  -e MCP_SERVER_CATALOG_URLS=http://host.docker.internal:4444/servers/UUID_OF_SERVER_1 \
  -e MCP_TOOL_CALL_TIMEOUT=120 \
  -e MCP_WRAPPER_LOG_LEVEL=DEBUG \
  ghcr.io/ibm/mcp-context-forge:0.3.1 \
  python3 -m mcpgateway.wrapper

Because the wrapper speaks JSON-RPC over stdin/stdout, you can interact with it using nothing more than a terminal or pipes.

# Start the MCP Gateway Wrapper

The mcpgateway.wrapper exposes everything your Gateway knows about over stdio, so any MCP client that can't (or shouldn't) open an authenticated SSE stream still gets full tool-calling power.

Remember to substitute your real Gateway URL (and server ID) for http://localhost:4444/servers/UUID_OF_SERVER_1. When inside Docker/Podman, that often becomes http://host.docker.internal:4444/servers/UUID_OF_SERVER_1 (macOS/Windows) or the gateway container's hostname (Linux).

2. Paste one of the JSON blocks above (Docker / pipx / uvx).
3. Restart the app so the new stdio server is spawned.
4. Open logs in the same menu to verify mcpgateway-wrapper started and listed your tools.

Need help? See:

• MCP Debugging Guide - https://modelcontextprotocol.io/docs/tools/debugging

Spin up a fully-loaded dev environment (Python 3.11, Docker/Podman CLI, all project dependencies) in just two clicks.

• VS Code with the Dev Containers extension
• Docker or Podman installed and running locally

git clone https://github.com/ibm/mcp-context-forge.git
cd mcp-context-forge
code .

VS Code will detect the .devcontainer and prompt: "Reopen in Container" or manually run: Ctrl/Cmd ⇧ P → Dev Containers: Reopen in Container

The container build will:

• Install system packages & Python 3.11
• Run make install-dev to pull all dependencies
• Execute tests to verify the toolchain

You'll land in /workspace ready to develop.

Common tasks inside the container:

# Start dev server (hot reload)
make dev            # http://localhost:4444

# Run tests & linters
make test
make lint

Optional:

• make bash - drop into an interactive shell
• make clean - clear build artefacts & caches
• Port forwarding is automatic (customize via .devcontainer/devcontainer.json)

No local Docker? Use Codespaces:

1. Go to the repo → Code ▸ Codespaces ▸ Create codespace on main
2. Wait for the container image to build in the cloud
3. Develop using the same workflow above

• Python ≥ 3.10
• GNU Make (optional, but all common workflows are available as Make targets)
• Optional: Docker / Podman for containerised runs

What it does:

1. Creates / activates a .venv in your home folder ~/.venv/mcpgateway
2. Installs the gateway and necessary dependencies
3. Launches Gunicorn (Uvicorn workers) on http://localhost:4444

For development, you can use:

make install-dev # Install development dependencies, ex: linters and test harness
make lint          # optional: run style checks (ruff, mypy, etc.)

You can use docker or podman, ex:

make podman            # build production image
make podman-run-ssl    # run at https://localhost:4444
# or listen on port 4444 on your host directly, adds --network=host to podman
make podman-run-ssl-host

curl -k -sX GET \
     -H "Authorization: Bearer $MCPGATEWAY_BEARER_TOKEN" \
     https://localhost:4444/tools | jq

You should receive [] until you register a tool.

make venv install          # create .venv + install deps
make serve                 # gunicorn on :4444

uv venv && source .venv/bin/activate
uv pip install -e '.[dev]' # IMPORTANT: in zsh, quote to disable glob expansion!

python3 -m venv .venv && source .venv/bin/activate
pip install -e ".[dev]"

You can configure the gateway with SQLite, PostgreSQL (or any other compatible database) in .env.

When using PostgreSQL, you need to install psycopg2 driver.

uv pip install psycopg2-binary   # dev convenience
# or
uv pip install psycopg2          # production build

docker run --name mcp-postgres \
  -e POSTGRES_USER=postgres \
  -e POSTGRES_PASSWORD=mysecretpassword \
  -e POSTGRES_DB=mcp \
  -p 5432:5432 -d postgres

A make compose-up target is provided along with a docker-compose.yml file to make this process simpler.

⚠️ If any required .env variable is missing or invalid, the gateway will fail fast at startup with a validation error via Pydantic.

You can get started by copying the provided .env.example to .env and making the necessary edits to fit your environment.

💡 Use APP_ROOT_PATH=/foo if reverse-proxying under a subpath like https://host.com/foo/.

🔐 BASIC_AUTH_USER/PASSWORD are used for:

• Logging into the web-based Admin UI
• Accessing APIs via Basic Auth (curl -H "Authorization: Bearer $MCPGATEWAY_BEARER_TOKEN")

🔑 JWT_SECRET_KEY is used to:

• Sign JSON Web Tokens (Authorization: Bearer <token>)

• Generate tokens via:

  export MCPGATEWAY_BEARER_TOKEN=$(python3 -m mcpgateway.utils.create_jwt_token --username admin --exp 0 --secret my-test-key)
  echo $MCPGATEWAY_BEARER_TOKEN

• Tokens allow non-interactive API clients to authenticate securely.

🧪 Set AUTH_REQUIRED=false during development if you want to disable all authentication (e.g. for local testing or open APIs) or clients that don't support SSE authentication. In production, you should use the SSE to stdio mcpgateway-wrapper for such tools that don't support authenticated SSE, while still ensuring the gateway uses authentication.

🔐 AUTH_ENCRYPTION_SECRET is used to encrypt and decrypt tool authentication credentials (auth_value). You must set the same value across environments to decode previously stored encrypted auth values. Recommended: use a long, random string.

🖥️ Set both to false to disable management UI and APIs in production.

Note: do not quote the ALLOWED_ORIGINS values, this needs to be valid JSON, such as: ALLOWED_ORIGINS=["http://localhost", "http://localhost:4444"]

🧠 none disables caching entirely. Use memory for dev, database for persistence, or redis for distributed caching.

 make serve               # Run production Gunicorn server on
 make serve-ssl           # Run Gunicorn behind HTTPS on :4444 (uses ./certs)

To run the development (uvicorn) server:

make dev
# or
./run.sh --reload --log debug --workers 2

run.sh is a wrapper around uvicorn that loads .env, supports reload, and passes arguments to the server.

Key flags:

uvicorn mcpgateway.main:app --host 0.0.0.0 --port 4444 --workers 4

# Generate a JWT token using JWT_SECRET_KEY and export it as MCPGATEWAY_BEARER_TOKEN
# Note that the module needs to be installed. If running locally use:
export MCPGATEWAY_BEARER_TOKEN=$(JWT_SECRET_KEY=my-test-key python3 -m mcpgateway.utils.create_jwt_token)

# Use the JWT token in an API call
curl -H "Authorization: Bearer $MCPGATEWAY_BEARER_TOKEN" http://localhost:4444/tools

Deployment details can be found in the GitHub Pages.

This project supports deployment to IBM Cloud Code Engine using the ibmcloud CLI and the IBM Container Registry.

• Podman or Docker installed locally
• IBM Cloud CLI (use make ibmcloud-cli-install to install)
• An IBM Cloud API key with access to Code Engine & Container Registry
• Code Engine and Container Registry services enabled in your IBM Cloud account

Create a .env file (or export the variables in your shell). The first block is required; the second provides tunable defaults you can override:

# ── Required ─────────────────────────────────────────────
IBMCLOUD_REGION=us-south
IBMCLOUD_RESOURCE_GROUP=default
IBMCLOUD_PROJECT=my-codeengine-project
IBMCLOUD_CODE_ENGINE_APP=mcpgateway
IBMCLOUD_IMAGE_NAME=us.icr.io/myspace/mcpgateway:latest
IBMCLOUD_IMG_PROD=mcpgateway/mcpgateway
IBMCLOUD_API_KEY=your_api_key_here   # Optional - omit to use interactive `ibmcloud login --sso`

# ── Optional overrides (sensible defaults provided) ──────
IBMCLOUD_CPU=1                       # vCPUs for the app
IBMCLOUD_MEMORY=4G                   # Memory allocation
IBMCLOUD_REGISTRY_SECRET=my-regcred  # Name of the Container Registry secret

✅ Quick check: make ibmcloud-check-env

make ibmcloud-check-env
make ibmcloud-cli-install
make ibmcloud-login
make ibmcloud-ce-login
make ibmcloud-tag
make ibmcloud-push
make ibmcloud-deploy
make ibmcloud-ce-status
make ibmcloud-ce-logs

You can test the API endpoints through curl, or Swagger UI, and check detailed documentation on ReDoc:

• Swagger UI → http://localhost:4444/docs
• ReDoc → http://localhost:4444/redoc

Generate an API Bearer token, and test the various API endpoints.

# Generate a bearer token using the configured secret key (use the same as your .env)
export MCPGATEWAY_BEARER_TOKEN=$(python3 -m mcpgateway.utils.create_jwt_token -u admin --secret my-test-key)
echo ${MCPGATEWAY_BEARER_TOKEN}

# Inside your WSL distro
ss -tlnp | grep 4444        # Use ss
netstat -anp | grep 4444    # or netstat

Seeing :::4444 LISTEN rootlessport is normal - the IPv6 wildcard socket (::) also accepts IPv4 traffic when net.ipv6.bindv6only = 0 (default on Linux).

WSL 2's NAT layer rewrites only the IPv6 side of the dual-stack listener. From Windows, http://127.0.0.1:4444 (or Docker Desktop's "localhost") therefore times-out.

# Inside the WSL distro
echo "wsl" | sudo tee /etc/containers/podman-machine
systemctl --user restart podman.socket

ss should now show 0.0.0.0:4444 instead of :::4444, and the service becomes reachable from Windows and the LAN.

Docker Desktop adds a "WSL integration" switch per-distro. Turn it on for your distro, restart Docker Desktop, then restart the container:

docker restart mcpgateway

Copy .env.example to .env first:

Then edit DATABASE_URL, JWT_SECRET_KEY, BASIC_AUTH_PASSWORD, etc. Missing or empty required vars cause a fast-fail at startup.

1. Fork the repo, create a feature branch.
2. Run make lint and fix any issues.
3. Keep make test green and 100% coverage.
4. Open a PR - describe your changes clearly.
