Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
US public libraries and branches near any address, with collections from the IMLS survey
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
You need to fill in: LIBRARYAPI_KEY
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

mcp-name: dev.libraryapi/libraryapi-mcp
MCP server for libraryapi.dev — US public library data for AI agents.
Expose library lookups as tools to any MCP-compatible AI assistant (Claude, Cursor, Copilot, etc.). Built on the federal IMLS Public Libraries Survey — public domain, commercially usable.
pip install libraryapi-mcp
Or run directly with uvx (no install needed):
uvx libraryapi-mcp
Add to ~/Library/Application Support/Claude/claude_desktop_config.json:
{
"mcpServers": { "libraryapi": { "command": "uvx", "args": ["libraryapi-mcp"], "env": { "LIBRARYAPI_KEY": "your_api_key_here" } } } }
{
"mcpServers": { "libraryapi": { "command": "uvx", "args": ["libraryapi-mcp"], "env": { "LIBRARYAPI_KEY": "your_api_key_here" } } } }

| Tool | Description |
|---|---|
find_libraries_near_address | Find the nearest branches to a US street address |
find_libraries_near_coordinates | Same, but from a lat/lng (skips geocoding) |
get_outlet | Full record for one branch outlet by ID |
search_libraries | Search library *systems* by name, state, or city |
get_library | Full system profile by FSCS ID |
get_state_summary | Statewide library totals |
Systems vs. outlets: a *system* is the administrative entity (e.g. "Chicago Public Library"); an *outlet* is an individual branch. Proximity searches return outlets.
Once configured, you can ask your AI assistant:
"What are the three closest public libraries to 350 Fifth Ave, New York?"
"How many public library branches are there in Vermont, and what's the total collection size?"
"I'm building a civic app — give me every library branch within 5 miles of downtown Chicago as JSON."
The IMLS survey covers locations, collections, staffing, visits, programs, and finances. It reports hours-open totals (annual, and per week) but not daily opening times — so this API can tell you a branch is open ~45 hours/week, not that it opens at 9am.
