Search LOC digital collections, browse Chronicling America newspapers with full OCR text, and look up LC Subject Headings via MCP. STDIO or Streamable HTTP.
Pick and run a multi-phase workflow that chains foundational task skills (`git-wrapup`, `release-and-publish`, `maintenance`, `field-test`, `setup`, etc.) end-to-end. Routes user intent to a workflow file under `workflows/` — greenfield builds, maintenance + release, field-test + fix, or known-work + release. Single source for the universal rules (no commits without authorization, no destructive git, no marketing language), the orchestrator posture (own the goal, ground sub-agents in primary sources, verify against the goal), and the sub-agent strategy (orient block, parallel fanout, isolation, normalization) that apply across every workflow. Sub-agents are an optional capability — workflows run linearly when fanout isn't available.
Finalize documentation and project metadata for a ship-ready MCP server. Use after implementation is complete, tests pass, and devcheck is clean. Safe to run at any stage — each step checks current state and only acts on what still needs work.
Ship a release end-to-end across every registry the project targets (npm, MCP Registry, GitHub Releases for `.mcpb` bundles, GHCR). Runs the final verification gate, pushes commits and tags, then publishes to each applicable destination. Assumes git wrapup (version bumps, changelog, commit, annotated tag) is already complete — this skill is the post-wrapup publish workflow. Retries transient network failures on publish steps; halts with a partial-state report when retries are exhausted or the failure is terminal.
File a bug or feature request against @cyanheads/mcp-ts-core when you hit a framework issue. Use when a builder, utility, context method, or config behaves contrary to the documented API — not for server-specific application bugs.
File a bug or feature request against this MCP server's own repo. Use for server-specific issues — tool logic, service integrations, config problems, or domain bugs that aren't caused by the framework.

Six tools covering the Library of Congress digital holdings — general search with format/date/subject/location filters, full item retrieval, Chronicling America newspaper search with OCR, single-page full-text fetch, LCSH subject heading lookup, and curated collection browsing:
| Tool | Description |
|---|---|
libofcongress_search | Search LOC digital collections by keyword with optional format, date range, subject heading, and geographic location filters. Returns item summaries with IDs for follow-up retrieval. |
libofcongress_get_item | Retrieve full metadata for a specific LOC item — contributors, subjects, rights, physical description, resource links (TIFF/JPEG/PDF), and related items. |
libofcongress_search_newspapers | Search historical newspaper pages in the Chronicling America corpus. Returns pages with OCR text excerpts (~500 chars), publication title, date, state, and the URL needed for libofcongress_get_newspaper_page. |
libofcongress_get_newspaper_page | Retrieve the full OCR text of a specific newspaper page. Pass the url field from a libofcongress_search_newspapers result. Returns ocr_available: false when the page has no digitized text. |
libofcongress_search_subjects | Search Library of Congress Subject Headings (LCSH) by keyword. Returns controlled-vocabulary labels and URIs — use the label as the subject filter in libofcongress_search. |
libofcongress_browse_collections | List and browse LOC curated digital collections with descriptions, item counts, and slugs. Optionally filter by keyword. |
