## Overview & Goals

**ContextForge** is a gateway, registry, and proxy that sits in front of any [Model Context Protocol](https://modelcontextprotocol.io) (MCP) server, A2A server or REST API-exposing a unified endpoint for all your AI clients. See the [project roadmap](https://ibm.github.io/mcp-context-forge/architecture/roadmap/) for more details.

It currently supports:

* Federation across multiple MCP and REST services
* **A2A (Agent-to-Agent) integration** for external AI agents (OpenAI, Anthropic, custom)
* **gRPC-to-MCP translation** via automatic reflection-based service discovery
* Virtualization of legacy APIs as MCP-compliant tools and servers
* Transport over HTTP, JSON-RPC, WebSocket, SSE (with configurable keepalive), stdio and streamable-HTTP
* An Admin UI for real-time management, configuration, and log monitoring (with airgapped deployment support)
* Built-in auth, retries, and rate-limiting with user-scoped OAuth tokens and unconditional X-Upstream-Authorization header support
* **OpenTelemetry observability** with Phoenix, Jaeger, Zipkin, and other OTLP backends
* Scalable deployments via Docker or PyPI, Redis-backed caching, and multi-cluster federation

<details>
<summary><strong>🚀 End-to-end demo (register a local MCP server)</strong></summary>

```bash
# 1️⃣  Spin up the sample GO MCP time server using mcpgateway.translate & docker (replace docker with podman if needed)
python3 -m mcpgateway.translate \
     --stdio "docker run --rm -i ghcr.io/ibm/fast-time-server:latest -transport=stdio" \
     --expose-sse \
     --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" --expose-sse --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" --expose-sse --port 8002

# NEW: Expose via multiple protocols simultaneously!
python3 -m mcpgateway.translate \
     --stdio "uvx mcp-server-git" \
     --expose-sse \
     --expose-streamable-http \
     --port 9000
# Now accessible via both /sse (SSE) and /mcp (streamable HTTP) endpoints

# 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:8003/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 '{"server":{"name":"time_server","description":"Fast time tools","associated_tools":[<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 '{"server":{"name":"time_server","description":"Fast time tools","associated_tools":["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 HTTP endpoint. Inspect it interactively with the MCP Inspector CLI (or use any MCP client)
npx -y @modelcontextprotocol/inspector
# Transport Type: Streamable HTTP, URL: http://localhost:4444/servers/UUID_OF_SERVER_1/mcp,  Header Name: "Authorization", Bearer Token
```

</details>

<details>
<summary><strong>🖧 Using the stdio wrapper (mcpgateway-wrapper)</strong></summary>

```bash
export MCP_AUTH="Bearer ${MCPGATEWAY_BEARER_TOKEN}"
export MCP_SERVER_URL=http://localhost:4444/servers/UUID_OF_SERVER_1/mcp
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` and `MCP_SERVER_URL` env variables, and select `python3` as the Command, and `-m mcpgateway.wrapper` as Arguments.

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

or

Pass the url and auth as arguments (no need to set environment variables)
```bash
npx -y @modelcontextprotocol/inspector
command as `python`
Arguments as `-m mcpgateway.wrapper --url "http://localhost:4444/servers/UUID_OF_SERVER_1/mcp" --auth "Bearer <your token>"`
```


When using a MCP Client such as Claude with stdio:

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

</details>

# Start with MariaDB (recommended for production)
docker compose up -d

# Or start with PostgreSQL
# Uncomment postgres in docker-compose.yml and comment mariadb section
# docker compose up -d

# Check status
docker compose ps

# View logs
docker compose logs -f gateway

# Access Admin UI: http://localhost:4444/admin (login with PLATFORM_ADMIN_EMAIL/PASSWORD)
# Generate API token
docker compose exec gateway python3 -m mcpgateway.utils.create_jwt_token \
  --username admin@example.com --exp 10080 --secret my-test-key
```

**What you get:**

<details>
<summary><strong>✏️ Docker/Podman tips</strong></summary>

* **.env files** - Put all the `-e FOO=` lines into a file and replace them with `--env-file .env`. See the provided [.env.example](https://github.com/IBM/mcp-context-forge/blob/main/.env.example) for reference.
* **Pinned tags** - Use an explicit version (e.g. `1.0.0-BETA-2`) instead of `latest` for reproducible builds.
* **JWT tokens** - Generate one in the running container:

  ```bash
  docker exec mcpgateway python3 -m mcpgateway.utils.create_jwt_token --username admin@example.com --exp 10080 --secret my-test-key
  ```
* **Upgrades** - Stop, remove, and rerun with the same `-v $(pwd)/data:/data` mount; your DB and config stay intact.

<summary><strong>🖧 Running the MCP Gateway stdio wrapper</strong></summary>

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.

```bash
# Set environment variables
export MCPGATEWAY_BEARER_TOKEN=$(python3 -m mcpgateway.utils.create_jwt_token --username admin@example.com --exp 10080 --secret my-test-key)

## Quick Start: VS Code Dev Container

Clone the repo and open in VS Code—it will detect `.devcontainer` and prompt to **"Reopen in Container"**. The container includes Python 3.11, Docker CLI, and all project dependencies.

For detailed setup, workflows, and GitHub Codespaces instructions, see **[Developer Onboarding](https://ibm.github.io/mcp-context-forge/development/developer-onboarding/)**.

---

## Installation

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

<details>
<summary><strong>Alternative: UV or pip</strong></summary>

```bash
# UV (faster)
uv venv && source .venv/bin/activate
uv pip install -e '.[dev]'

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

</details>

<details>
<summary><strong>PostgreSQL adapter setup</strong></summary>

Install the `psycopg` driver for PostgreSQL:

```bash
# Install system dependencies first
# Debian/Ubuntu: sudo apt-get install libpq-dev
# macOS: brew install libpq

uv pip install 'psycopg[binary]'   # dev (pre-built wheels)
# or: uv pip install 'psycopg[c]'  # production (requires compiler)
```

Connection URL format:
```bash
DATABASE_URL=postgresql+psycopg://user:password@localhost:5432/mcp
```

Quick Postgres container:
```bash
docker run --name mcp-postgres \
  -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=mysecretpassword \
  -e POSTGRES_DB=mcp -p 5432:5432 -d postgres

## Configuration

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

Copy the provided [.env.example](https://github.com/IBM/mcp-context-forge/blob/main/.env.example) to `.env` and update the security-sensitive values below.

### 🔐 Required: Change Before Use

These variables have insecure defaults and **must be changed** before production deployment:

| Variable | Description | Default | Action Required |
|----------|-------------|---------|-----------------|
| `JWT_SECRET_KEY` | Secret key for signing JWT tokens (32+ chars) | `my-test-key` | Generate with `openssl rand -hex 32` |
| `AUTH_ENCRYPTION_SECRET` | Passphrase for encrypting stored credentials | `my-test-salt` | Generate with `openssl rand -hex 32` |
| `BASIC_AUTH_USER` | Username for HTTP Basic auth | `admin` | Change for production |
| `BASIC_AUTH_PASSWORD` | Password for HTTP Basic auth | `changeme` | Set a strong password |
| `PLATFORM_ADMIN_EMAIL` | Email for bootstrap admin user | `admin@example.com` | Use real admin email |
| `PLATFORM_ADMIN_PASSWORD` | Password for bootstrap admin user | `changeme` | Set a strong password |
| `PLATFORM_ADMIN_FULL_NAME` | Display name for bootstrap admin | `Admin User` | Set admin name |

### 🔒 Security Defaults (Secure by Default)

These settings are enabled by default for security—only disable for backward compatibility:

| Variable | Description | Default |
|----------|-------------|---------|
| `REQUIRE_JTI` | Require JTI claim in tokens for revocation support | `true` |
| `REQUIRE_TOKEN_EXPIRATION` | Require exp claim in tokens | `true` |
| `PUBLIC_REGISTRATION_ENABLED` | Allow public user self-registration | `false` |

### ⚙️ Project Defaults (Dev Setup)

These values differ from code defaults to provide a working local/dev setup:

| Variable | Description | Default |
|----------|-------------|---------|
| `HOST` | Bind address | `0.0.0.0` |
| `MCPGATEWAY_UI_ENABLED` | Enable Admin UI dashboard | `true` |
| `MCPGATEWAY_ADMIN_API_ENABLED` | Enable Admin API endpoints | `true` |
| `DATABASE_URL` | SQLAlchemy connection URL | `sqlite:///./mcp.db` |
| `SECURE_COOKIES` | Set `false` for HTTP (non-HTTPS) dev | `true` |

### 📚 Full Configuration Reference

For the complete list of 300+ environment variables organized by category (authentication, caching, SSO, observability, etc.), see the **[Configuration Reference](https://ibm.github.io/mcp-context-forge/manage/configuration/)**.

## Running

### Quick Reference

| Command | Server | Port | Database | Use Case |
|---------|--------|------|----------|----------|
| `make dev` | Uvicorn | **8000** | SQLite | Development (single instance, auto-reload) |
| `make serve` | Gunicorn | **4444** | SQLite | Production single-node (multi-worker) |
| `make serve-ssl` | Gunicorn | **4444** | SQLite | Production single-node with HTTPS |
| `make compose-up` | Docker Compose + Nginx | **8080** | PostgreSQL + Redis | Full stack (3 replicas, load-balanced) |
| `make testing-up` | Docker Compose + Nginx | **8080** | PostgreSQL + Redis | Testing environment |

### Development Server (Uvicorn)

```bash
make dev                 # Uvicorn on :8000 with auto-reload and SQLite
# 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:

| Flag             | Purpose          | Example            |
| ---------------- | ---------------- | ------------------ |
| `-e, --env FILE` | load env-file    | `--env prod.env`   |
| `-H, --host`     | bind address     | `--host 127.0.0.1` |
| `-p, --port`     | listen port      | `--port 8080`      |
| `-w, --workers`  | gunicorn workers | `--workers 4`      |
| `-r, --reload`   | auto-reload      | `--reload`         |

### Production Server (Gunicorn)

```bash
make serve               # Gunicorn on :4444 with multiple workers
make serve-ssl           # Gunicorn behind HTTPS on :4444 (uses ./certs)
```

### Docker Compose (Full Stack)

```bash
make compose-up          # Start full stack: PostgreSQL, Redis, 3 gateway replicas, Nginx on :8080
make compose-logs        # Tail logs from all services
make compose-down        # Stop the stack
```

### Manual (Uvicorn)

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

## Troubleshooting

Common issues and solutions:

| Issue | Quick Fix |
|-------|-----------|
| SQLite "disk I/O error" on macOS | Avoid iCloud-synced directories; use `~/mcp-context-forge/data` |
| Port 4444 not accessible on WSL2 | Configure WSL integration in Docker Desktop |
| Gateway exits immediately | Copy `.env.example` to `.env` and configure required vars |
| `ModuleNotFoundError` | Run `make install-dev` |
