Audiobookshelf MCP Server
A Go MCP server for inspecting and safely operating Audiobookshelf libraries.
abs-mcp exposes safe, typed MCP tools and resources for agents that need to inspect Audiobookshelf libraries, diagnose scans, and optionally trigger bounded maintenance workflows.
ABS_READ_ONLY=false.I built this MCP server to work especially well alongside jeeftor/audiobook-organizer. While it exposes the normal Audiobookshelf MCP tools for inspecting libraries, items, metadata, and server state, one of its most useful workflows is auditing whether books are actually organized the way you expect on disk.
The abs_find_misorganized_items tool checks Audiobookshelf item paths against supported folder layout conventions, including author/title and author/series/title structures. It is audit-only, so it reports likely misconfigured or misplaced books without moving or deleting files. That makes it a good companion to Audiobook Organizer: use this MCP server to identify layout problems from Audiobookshelf's perspective, then use Audiobook Organizer to clean up or standardize the underlying files.
This comparison is generated from public GitHub repository metadata, public project READMEs, registry/package searches, and this repository's current docs. It is descriptive rather than a recommendation.
Mutating versus non-mutating coverage:
jeeftor/abs-mcp exposes read-only inspection, search, author, series, collection, current-user progress/bookmark/listening reads, backups, ereader device discovery, ebook send preview, metadata-object, layout-audit, resources, and prompts by default. Ebook device-send tools perform outbound delivery but do not mutate Audiobookshelf library, metadata, backup, progress, collection, or playlist state, so they remain usable in read-only mode. Scan, cleanup, cover, chapter, progress/bookmark writes, backup creation, metadata, and collection/playlist create/update/add/delete/remove tools can mutate Audiobookshelf state only when ABS_READ_ONLY=false; destructive operations also require exact confirmation strings.michaeldvinci/audiobookshelf-mcp exposes a broad management surface with read tools plus mutating operations such as library, collection, playlist, progress, and backup actions. No public README evidence was found for a global default read-only gate during this pass.sandymac/audiobookshelf-mcp is mostly read/query oriented, with optional progress and bookmark mutation tools that are disabled by default.sierikov/audiobookshelf-mcp presents a read-only browsing, search, progress, stats, author, series, and collection surface.ForceConstant/audiobookshelf_mcp appears to be generated from Audiobookshelf OpenAPI material; mutating coverage and safety gates were not determinable from the public README.Sources checked in this pass:
michaeldvinci/audiobookshelf-mcp, sandymac/audiobookshelf-mcp, sierikov/audiobookshelf-mcp, ForceConstant/audiobookshelf_mcp, and schmidt-software/mcp-audiobookshelf.| Server | Shape | Confirmed strengths | Safety posture | Difference from jeeftor/abs-mcp |
|---|---|---|---|---|
michaeldvinci/audiobookshelf-mcp | Go stdio server with release binaries; GitHub metadata showed latest release 0.0.5 on 2025-11-11. | Broad general Audiobookshelf management, including libraries, items, authors, collections, playlists, user info, sessions, podcasts, progress updates, and backups. | Exposes mutating tools; no global default read-only gate was found in the public README during this comparison pass. | Broader generic management surface, but less conservative. This server overlaps more typed repair/catalog workflows now while adding default read-only gating, destructive confirmations, source-backed API inventory, MCP resources/prompts, organizer-oriented audit tooling, and fixture-backed behavior checks. |
sandymac/audiobookshelf-mcp | Rust server with stdio plus HTTP/SSE support. | Read/query surface for libraries, search, progress, stats, recent sessions, and optional progress/bookmark mutations. | Mutating tools are disabled by default and must be explicitly enabled. HTTP mode recommends bearer auth and TLS proxying. | Similar safety model. It keeps the mutating surface narrow; this server adds source-backed API inventory, resources/prompts, organizer-oriented audits, fixture workflows, typed metadata/cover/chapter/catalog tools, and explicit destructive confirmations. |
sierikov/audiobookshelf-mcp | Go server with read-oriented tooling, release binaries, .mcpb Claude Desktop bundles, and an MCP Registry entry. | Read-only browsing and search across libraries, items, progress, stats, sessions, series, authors, and collections. | Public README presents all tools as read-only with no writes, playback control, or user management. | Overlaps this server's read-only browsing surface, including progress, author, series, and collection reads, but no public evidence was found for controlled repair/catalog mutation workflows, source-backed API inventory, MCP prompts/resources, organizer-focused audit tooling, or Docker fixture workflows. |
ForceConstant/audiobookshelf_mcp | Generated OpenAPI MCP bridge with Streamable HTTP on port 3000 and Docker-oriented files. | Broad generated API exposure from Audiobookshelf OpenAPI material. | Not determinable from the public README; generated API exposure may include mutating endpoints, but the README does not enumerate safety controls. | Less curated and less operator-specific. This project intentionally exposes bounded, typed tools with read-only gating and fixture-backed behavior checks instead of exposing every route directly. |
Weak or placeholder hits, such as schmidt-software/mcp-audiobookshelf, were excluded when no implementation or feature evidence was available.

abs_match_itemabs_update_item_tracksTools that mutate Audiobookshelf state are blocked by default because ABS_READ_ONLY defaults to true. Scan tools, issue cleanup, cover updates, chapter updates, typed item metadata, current-user progress/bookmark writes, backup creation, and collection/playlist create, update, add-item, delete, and remove-item tools are implemented mutating operations. Ebook send-to-device delivery and guarded query-based device send only email an already-existing ebook file out; they create, change, or delete nothing on Audiobookshelf (library, metadata, backup, progress, collection, or playlist state), so they are allowed while read-only mode is enabled. Read-only here means "does not mutate Audiobookshelf state," not "produces no outbound side effect"; if you need to suppress device delivery entirely, do not configure an ereader device.
