Overview

HDHomeRun MCP MCP Server + A2A Agent

A complete client + MCP server + A2A agent for SiliconDust HDHomeRun network TV tuners, covering all four of SiliconDust's documented interfaces: the HTTP JSON API (device discovery, channel lineup, scan control), the DVR API (SiliconDust cloud recording rules + local record-engine operations), the Discovery API (local UDP broadcast on port 65001 + the cloud discovery endpoint), and the binary hdhomerun_config control protocol (TCP port 65001 — a different wire protocol from the HTTP API, used for per-tuner status/vstatus/streaminfo/tuning/filters). Also ships a doctor diagnostic tool matching this fleet's cm_doctor convention.

This repository is actively maintained - Contributions are welcome!

Key Features

• All four HDHomeRun interfaces, one package — HTTP JSON API, DVR API, Discovery API (local UDP + cloud), and the binary hdhomerun_config control protocol, each its own action-routed tool domain.
• doctor diagnostics — one call checks device reachability, firmware/model, tuner count vs. a paired Jellyfin instance, per-channel signal strength, DeviceAuth presence/validity, and discovery-cache freshness — pass/fail with an actionable next step per check.
• Action-routed MCP tools — each domain is exposed as a single MCP tool that routes to multiple underlying operations via an action argument, keeping the tool surface small.
• Two interfaces, one package — use it as a Python API client, an MCP server (stdio / streamable-http / sse).
• agent-connector-sdk native — built on the shared framework (auth, action router, telemetry, governance) for fleet consistency.
• Per-tool toggles — enable or disable each tool domain with environment switches.
• Enterprise-ready — OTEL/Langfuse telemetry and optional Eunomia access governance.

Available MCP Tools

Each tool is action-routed: pass an action and a JSON params_json payload. Tool domains can be toggled on or off with the listed environment variable. The table below is auto-generated from the live server by the mcp-readme-table pre-commit hook (python -m agent_connector_sdk.mcp.readme_tools) — do not edit it by hand.

5 action-routed tool(s) · 57 verbose 1:1 tool(s). Each is enabled unless its <DOMAIN>TOOL toggle is set false; MCP_TOOL_MODE selects the surface (intent default — the six verb-tools, granular set loaded on demand · condensed action-routed · verbose 1:1 · both). Auto-generated — do not edit.

Installation

Install with uvx (no install — run on demand)

uvx --from "hdhomerun-mcp[mcp]" hdhomerun-mcp      # MCP server (slim deps)

The [mcp] extra installs only the FastMCP/FastAPI MCP-server tooling (agent-connector-sdk) — it excludes the heavy agent runtime (the epistemic-graph engine, pydantic-ai, dspy, llama-index), so it is far

Install with pip

python -m pip install hdhomerun-mcp            # core (API client)
python -m pip install "hdhomerun-mcp[all]"     # + MCP server + A2A agent + telemetry

Console scripts

After installation the following entry points are available on the operator's PATH:

Command	Description
hdhomerun-mcp	Start the MCP server

Usage

As a Python API client

from hdhomerun_mcp.auth import get_client

client = get_client()  # reads HDHOMERUN_URL / HDHOMERUN_DEVICE_AUTH
info = client.get_discover()  # device identity + tuner count
lineup = client.get_lineup()  # channel list
stream_url = client.build_stream_url("24.1")  # http://<device>:5004/auto/v24.1
report = client.run_doctor()  # full health-check sweep

As an MCP server (CLI)

# Local stdio (for IDEs)
hdhomerun-mcp

# Networked streamable-http
hdhomerun-mcp --transport streamable-http --host 0.0.0.0 --port 8000

Calling an MCP tool

Tools are action-routed — pass an action plus a JSON params_json string:

{
  "tool": "http_operations",
  "arguments": {
    "action": "discover",
    "params_json": "{}"
  }
}

MCP

Using as an MCP Server

The MCP Server can be run in stdio (local), streamable-http (networked), or sse mode.

MCP Configuration Examples

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

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

        "hdhomerun-mcp"
      ],

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

Streamable-HTTP Transport (networked / production)

{
  "mcpServers": {
    "hdhomerun-mcp": {
      "command": "uvx",
      "args": [
        "--from",
        "hdhomerun-mcp[mcp]",
        "hdhomerun-mcp",
        "--transport",
        "streamable-http",
        "--port",
        "8000"
      ],
      "env": {
        "TRANSPORT": "streamable-http",

        "HDHOMERUN_URL": "http://hdhomerun.local",
        "HTTPTOOL": "True"
      }
    }
  }
}

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

{
  "mcpServers": {
    "hdhomerun-mcp": {
      "url": "http://localhost:8000/hdhomerun-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 CONFIGTOOL=True \
  -e DISCOVERYTOOL=True \
  -e DOCTORTOOL=True \
  -e DVRTOOL=True \
  -e HDHOMERUN_DEVICE_AUTH=your_device_auth_here \
  -e HDHOMERUN_URL=http://hdhomerun.local \
  -e HTTPTOOL=True \
  registry.example.invalid/hdhomerun-mcp@sha256:<digest> hdhomerun-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

hdhomerun-mcp can also run as a local container (Docker / Podman / uv) or be consumed from a remote deployment. The Deployment guide has full, copy-paste mcp_config.json for all four transports — stdio, streamable-http, local container / uv, and remote URL:

• Local container / uv — launch the server from mcp_config.json via uvx, docker run, or podman run, or point at a local streamable-http container by url.
• Remote URL — connect to a server deployed behind Caddy at https://hdhomerun-mcp.example.invalid/mcp using the "url" key.

Container images (:mcp)

One multi-stage docker/Dockerfile builds the MCP-only image (--target mcp):

Image tag	Build target	Contents	Entrypoint
knucklessg1/hdhomerun-mcp:mcp	--target mcp	hdhomerun-mcp[mcp] — slim, no engine/pydantic-ai/dspy/llama-index	hdhomerun-mcp

docker build --target mcp   -t knucklessg1/hdhomerun-mcp:mcp    docker/   # slim MCP server

Knowledge-graph database (epistemic-graph)

agent-connector-sdk). For production — or to share one knowledge graph across multiple agents — run epistemic-graph as its own database container and point the agent at it. Deployment recipes (single-node + Raft HA), connection config, and the full database architecture (with diagrams) are in the epistemic-graph deployment guide. The slim [mcp] server does not require the database.

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, Arbora delegation, or trace export.
