Deployment¶

Deployment Options¶

owncast-agent exposes its MCP server (console script owncast-mcp) four ways. Pick the row that matches where the server runs relative to your MCP client, then copy the matching mcp_config.json below. Replace the <your-…> placeholders with the values from the Configuration / Environment Variables section.

#	Option	Transport	Where it runs	`mcp_config.json` key
1	stdio	`stdio`	client launches a subprocess	`command`
2	Streamable-HTTP (local)	`streamable-http`	a local network port	`command` or `url`
3	Local container / uv	`stdio` or `streamable-http`	Docker / Podman / uv on this host	`command` or `url`
4	Remote URL	`streamable-http`	a remote host behind Caddy	`url`

1. stdio (local subprocess)¶

The client launches the server over stdio via uvx — best for local IDEs (Cursor, Claude Desktop, VS Code):

{
  "mcpServers": {
    "owncast-mcp": {
      "command": "uvx",
      "args": ["--from", "owncast-agent", "owncast-mcp"],
      "env": {
        "OWNCAST_URL": "<your-owncast_url>",
        "OWNCAST_TOKEN": "<your-owncast_token>"
      }
    }
  }
}

2. Streamable-HTTP (local process)¶

Run the server as a long-lived HTTP process:

uvx --from owncast-agent owncast-mcp --transport streamable-http --host 0.0.0.0 --port 8000
curl -s http://localhost:8000/health        # {"status":"OK"}

Then either let the client launch it:

{
  "mcpServers": {
    "owncast-mcp": {
      "command": "uvx",
      "args": ["--from", "owncast-agent", "owncast-mcp", "--transport", "streamable-http", "--port", "8000"],
      "env": {
        "TRANSPORT": "streamable-http",
        "HOST": "0.0.0.0",
        "PORT": "8000",
        "OWNCAST_URL": "<your-owncast_url>",
        "OWNCAST_TOKEN": "<your-owncast_token>"
      }
    }
  }
}

…or connect to the already-running process by URL:

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

3. Local container / uv¶

(a) Launch a container directly from mcp_config.json (stdio over the container — no ports to manage). Swap docker for podman for a daemonless runtime:

{
  "mcpServers": {
    "owncast-mcp": {
      "command": "docker",
      "args": [
        "run", "-i", "--rm",
        "-e", "TRANSPORT=stdio",
        "-e", "OWNCAST_URL=<your-owncast_url>",
        "-e", "OWNCAST_TOKEN=<your-owncast_token>",
        "knucklessg1/owncast-agent:latest"
      ]
    }
  }
}

(b) Run a local streamable-http container, then connect by URL:

docker run -d --name owncast-mcp -p 8000:8000 \
  -e TRANSPORT=streamable-http \
  -e PORT=8000 \
  -e OWNCAST_URL="<your-owncast_url>" \
  -e OWNCAST_TOKEN="<your-owncast_token>" \
  knucklessg1/owncast-agent:latest
# or, from a clone of this repo:
docker compose -f docker/mcp.compose.yml up -d

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

(c) From a local checkout with uv:

uv run owncast-mcp --transport streamable-http --port 8000

4. Remote URL (deployed behind Caddy)¶

When the server is deployed remotely (e.g. as a Docker service) and published through Caddy on the internal *.arpa zone, connect with the "url" key — no local process or image required:

{
  "mcpServers": {
    "owncast-mcp": { "url": "http://owncast-mcp.arpa/mcp" }
  }
}

Caddy reverse-proxies http://owncast-mcp.arpa to the container's :8000 streamable-http listener; http://owncast-mcp.arpa/health returns {"status":"OK"} when the service is live.

This page covers running owncast-agent as a long-lived server: the transports, a Docker Compose stack, the optional A2A agent server, putting it behind a Caddy reverse proxy, and giving it a DNS name with Technitium. To provision the Owncast server it connects to, see Backing Platform.

owncast-agent ships an MCP server (console script owncast-mcp) and a companion A2A agent server (console script owncast-agent). The MCP server is a typed, deterministic tool surface a policy router / agent calls; the agent server is a Pydantic-AI agent that consumes those tools.

Run the MCP server¶

The transport is selected with --transport (or the TRANSPORT env var):

stdio (default)streamable-httpsse

owncast-mcp

For IDE / desktop MCP clients that launch the server as a subprocess.

owncast-mcp --transport streamable-http --host 0.0.0.0 --port 8000

A network server with a /health endpoint and /mcp route.

owncast-mcp --transport sse --host 0.0.0.0 --port 8000

Health check (HTTP transports):

curl -s http://localhost:8000/health        # {"status":"OK"}

Configuration (environment)¶

owncast-agent is configured entirely from the environment. The required set:

Var	Default	Meaning
`OWNCAST_URL`	`http://localhost:9000`	Owncast server base URL
`OWNCAST_TOKEN`	(empty)	Owncast admin / integration access token
`TRANSPORT`	`stdio`	MCP transport: `stdio`, `streamable-http`, `sse`
`HOST`	`0.0.0.0`	Bind address (HTTP transports)
`PORT`	`8000`	Bind port (HTTP transports)
`INTERNALTOOL`	`True`	Register the `internal` tool group
`OBJECTSTOOL`	`True`	Register the `objects` tool group
`EXTERNALTOOL`	`True`	Register the `external` tool group
`CHATTOOL`	`True`	Register the `chat` tool group

Optional telemetry and access-governance settings (ENABLE_OTEL, OTEL_*, EUNOMIA_*, DEFAULT_AGENT_NAME) are documented in .env.example. Copy it to .env and fill in only what you use.

Docker Compose¶

The repo ships docker/mcp.compose.yml. It reads a sibling .env and publishes the HTTP server on :8000:

services:
  owncast-agent-mcp:
    image: knucklessg1/owncast-agent:latest
    container_name: owncast-agent-mcp
    hostname: owncast-agent-mcp
    restart: always
    env_file:
      - ../.env
    environment:
      - PYTHONUNBUFFERED=1
      - HOST=0.0.0.0
      - PORT=8000
      - TRANSPORT=streamable-http
    ports:
      - "8000:8000"
    healthcheck:
      test: ["CMD", "python3", "-c", "import urllib.request; urllib.request.urlopen('http://localhost:8000/health')"]
      interval: 30s
      timeout: 10s
      retries: 3

cp .env.example .env          # then edit OWNCAST_URL / OWNCAST_TOKEN
docker compose -f docker/mcp.compose.yml up -d
docker compose -f docker/mcp.compose.yml logs -f

A2A agent server¶

owncast-agent also ships a Pydantic-AI agent server (console script owncast-agent). It connects to the MCP server over HTTP and exposes an A2A / AG-UI endpoint, optionally with a web interface and OpenTelemetry tracing.

export OWNCAST_URL=http://your-owncast:8080
export OWNCAST_TOKEN=your_owncast_token
owncast-agent --provider openai --model-id gpt-4o --api-key sk-...

The repo ships docker/agent.compose.yml, which runs the MCP server and the agent server together. The agent listens on :9004 and reaches the MCP server by container name through MCP_URL:

services:
  owncast-agent-mcp:
    image: knucklessg1/owncast-agent:latest
    hostname: owncast-agent-mcp
    env_file: [../.env]
    environment:
      - HOST=0.0.0.0
      - PORT=8000
      - TRANSPORT=streamable-http
    ports: ["8000:8000"]

  owncast-agent-agent:
    image: knucklessg1/owncast-agent:latest
    depends_on: [owncast-agent-mcp]
    command: ["owncast-agent"]
    env_file: [../.env]
    environment:
      - HOST=0.0.0.0
      - PORT=9004
      - MCP_URL=http://owncast-agent-mcp:8000/mcp
      - PROVIDER=${PROVIDER:-openai}
      - MODEL_ID=${MODEL_ID:-gpt-4o}
      - ENABLE_WEB_UI=True
    ports: ["9004:9004"]

docker compose -f docker/agent.compose.yml up -d

Behind a Caddy reverse proxy¶

Expose the HTTP server on a hostname with automatic TLS. Add to your Caddyfile:

# Internal (self-signed) — homelab .arpa zone
owncast-agent.arpa {
    tls internal
    reverse_proxy owncast-agent-mcp:8000
}

# Public — automatic Let's Encrypt
owncast-agent.example.com {
    reverse_proxy owncast-agent-mcp:8000
}

Reload Caddy:

docker compose -f services/caddy/compose.yml exec caddy caddy reload --config /etc/caddy/Caddyfile

DNS with Technitium¶

Point the hostname at the host running Caddy. Via the Technitium API:

curl -s "http://technitium.arpa:5380/api/zones/records/add" \
  --data-urlencode "token=$TECHNITIUM_DNS_TOKEN" \
  --data-urlencode "domain=owncast-agent.arpa" \
  --data-urlencode "zone=arpa" \
  --data-urlencode "type=A" \
  --data-urlencode "ipAddress=10.0.0.10" \
  --data-urlencode "ttl=3600"

…or add an A record owncast-agent.arpa → <caddy-host-ip> in the Technitium web console (http://technitium.arpa:5380). The ecosystem technitium-dns-mcp automates this as a tool.

Register with an MCP client¶

Add to your client's mcp_config.json:

{
  "mcpServers": {
    "owncast-agent": {
      "command": "uv",
      "args": ["run", "owncast-mcp"],
      "env": {
        "OWNCAST_URL": "http://your-owncast:8080",
        "OWNCAST_TOKEN": "your_owncast_token"
      }
    }
  }
}

For a remote HTTP server, point the client at http://owncast-agent.arpa/mcp instead.
