Overview

Audiobookshelf API client + MCP Server

The package exposes an operator-selected Audiobookshelf service through typed, action-routed tools without storing an endpoint, credential, or instance profile.

This repository is actively maintained - Contributions are welcome!

Key Features

• 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.
• Checked transport profiles — outbound HTTP uses AgentConfig-backed TLS trust; peer and hostname verification cannot be disabled by this connector.
• Governed graph capability inputs — ships one complete skill, a public-model ontology, and a neutral source preset, but no direct graph-write or raw-media tool.
• 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.

6 action-routed tool(s) · 46 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 "audiobookshelf-mcp[mcp]" audiobookshelf-mcp      # MCP server

Install with pip / uv

Pick the extra that matches what the operator want to run:

Extra	Installs	Use when
audiobookshelf-mcp[mcp]	MCP server (agent-connector-sdk) plus the mandatory full epistemic-graph base runtime	The operator run the MCP server
audiobookshelf-mcp[all]	MCP + test tooling	Development

# MCP server only (recommended for tool hosting)
uv pip install "audiobookshelf-mcp[mcp]"

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

Container images (:mcp)

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

Image tag	Build target	Contents	Entrypoint
audiobookshelf-mcp:mcp	--target mcp	MCP server plus the mandatory full epistemic-graph base dependency	audiobookshelf-mcp

docker build --target mcp -t audiobookshelf-mcp:mcp -f docker/Dockerfile .

Knowledge-graph database (epistemic-graph)

Every install receives epistemic-graph[full] through the current Agent Connector SDK base dependency. The connector does not open an insecure engine listener or silently select a machine-specific engine. Deployment topology and identity are resolved by AgentConfig. For a shared production authority, follow the epistemic-graph deployment guide.

Console scripts

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

Command	Description
audiobookshelf-mcp	Start the MCP server

Usage

As a Python API client

from audiobookshelf_mcp.auth import get_client

client = get_client()
try:
    print(client.get_libraries())
finally:
    client.close()

As an MCP server (CLI)

# Local stdio (for IDEs)
audiobookshelf-mcp

# Networked streamable-http
audiobookshelf-mcp --transport streamable-http --host 127.0.0.1 --port 8000

Calling an MCP tool

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

{
  "tool": "library_operations",
  "arguments": {
    "action": "list",
    "params_json": "{}"
  }
}

MCP

MCP Configuration Examples

Install the connector-focused [mcp] extra. Examples use audiobookshelf-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)

{
  "mcpServers": {
    "audiobookshelf-mcp": {
      "command": "uvx",
      "args": [
        "--from",
        "audiobookshelf-mcp[mcp]",
        "audiobookshelf-mcp"
      ],
      "env": {
        "MCP_TOOL_MODE": "intent",
        "AUDIOBOOKSHELF_TOKEN": "env://AUDIOBOOKSHELF_TOKEN",
        "AUDIOBOOKSHELF_URL": "env://AUDIOBOOKSHELF_URL",
        "AUTHORSTOOL": "True",
        "EMAILTOOL": "True",
        "LIBRARIESTOOL": "True",
        "NOTIFICATIONTOOL": "True",
        "PODCASTSTOOL": "True",
        "SERIESTOOL": "True"
      }
    }
  }
}

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": {
    "audiobookshelf-mcp": {
      "command": "uvx",
      "args": [
        "--from",
        "audiobookshelf-mcp[mcp]",
        "audiobookshelf-mcp",
        "--transport",
        "streamable-http",
        "--port",
        "8000"
      ],
      "env": {
        "TRANSPORT": "streamable-http",
        "HOST": "127.0.0.1",
        "PORT": "8000",
        "MCP_TOOL_MODE": "intent",
        "AUDIOBOOKSHELF_TOKEN": "env://AUDIOBOOKSHELF_TOKEN",
        "AUDIOBOOKSHELF_URL": "env://AUDIOBOOKSHELF_URL",
        "AUTHORSTOOL": "True",
        "EMAILTOOL": "True",
        "LIBRARIESTOOL": "True",
        "NOTIFICATIONTOOL": "True",
        "PODCASTSTOOL": "True",
        "SERIESTOOL": "True"
      }
    }
  }
}

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

{
  "mcpServers": {
    "audiobookshelf-mcp": {
      "url": "http://localhost:8000/audiobookshelf-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 AUDIOBOOKSHELF_TOKEN \
  -e AUDIOBOOKSHELF_URL \
  -e AUTHORSTOOL=True \
  -e EMAILTOOL=True \
  -e LIBRARIESTOOL=True \
  -e NOTIFICATIONTOOL=True \
  -e PODCASTSTOOL=True \
  -e SERIESTOOL=True \
  registry.example.invalid/audiobookshelf-mcp@sha256:<digest> audiobookshelf-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

audiobookshelf-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.

The generated table is the authoritative process-variable catalog. Endpoint and credential examples are unresolved references, not deployment values. AgentConfig owns TLS selection, OIDC delegation, runtime secret resolution, and observability policy; see Configuration, trust, and privacy for those typed profiles.

Governed capability contract

This package owns the complete release-generated schema-v2 capability bundle: connector_manifest.yml, the exact local MCP schema fingerprint, the Audiobookshelf ontology, SHACL shapes, the neutral source mapping and fixture, the migration ledger, and an offline source attestation. Release tooling derives and signs these artifacts from the current tool and ontology sources; they are not hand-authored and do not claim external-live certification.

Runtime endpoints, credentials, certificate trust, identity, tenant/ACL policy, retention, and observability destinations are deployment inputs and are never packaged values. See Configuration, trust, and privacy before enabling a network transport, Arbora delegation, governed source synchronization, or trace export.
