Agent-ready local document context with stable anchors.
File AI MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. Agent-ready local document context with stable anchors.
Read-only document awareness MCP server for agents. File AI uses Flyfish File Viewer core as the source of truth for format recognition, then turns local files into a stable profile, anchors, blocks, chunks, outline, search results, and contextual snippets so an agent can understand document content without reverse-engineering PDF, OOXML, spreadsheet, email, or archive internals.
Once File AI is connected, these are the calls the assistant has available:
doc_analyze — parse a local file and cache a document indexdoc_read — read blocks, chunks, or anchors from an existing index or pathdoc_search — search cached content with source anchorsdoc_context — retrieve nearby blocks around an anchor or querydoc_list_formats — list File Viewer core registry formats, all supported extensions, renderer capabilities, and File AI extractor coverage@flyfish-dev/file-ai on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. File AI's toolset — doc_analyze, doc_read, doc_search and 2 more — is a fair guide to whether it matches your workflow. It is maintained by flyfish-dev; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
