Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Agent integration with the Northwestern University Libraries Digital Collections API
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.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 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.
The registry does not list a required key, though some servers ask you to sign in on first use.
Either way works: install it on your computer or connect to the cloud version.
The GitHub repo last changed –, and the latest version (2.12.0) reached the registry 9 days ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

A Model Context Protocol (MCP) server that exposes Northwestern University Library's Digital Collections as tools for AI assistants. It provides tools for searching, browsing, and retrieving metadata and IIIF manifests for digitized library materials.
| Tool | Description |
|---|---|
search | Search for works using field-based and/or natural language queries |
similarity-search | Find works visually or semantically similar to a given work |
get-work | Retrieve full metadata for a single work by ID |
view-work | View a work's IIIF manifest for display in compatible viewers |
list-collections | List available digital collections |
view-collection | Browse a specific collection's IIIF manifest |
view-search-results | Retrieve results from a previous search |
view-similar-works | Retrieve results from a previous similarity search |
The server is available as a hosted remote at:
https://api.dc.library.northwestern.edu/api/v2/mcp
No local installation is required. Configure your MCP client to connect to this URL using the streamable HTTP transport.
Add the following to your Claude Desktop configuration file.
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json
{
"mcpServers": { "dc-api": { "type": "http", "url": "https://api.dc.library.northwestern.edu/api/v2/mcp" } } }
claude mcp add --transport http dc-api https://api.dc.library.northwestern.edu/api/v2/mcp
bin/run.sh to activate the correct runtime)npm install
The server reads the following environment variables:
| Variable | Default | Description |
|---|---|---|
DC_API_BASE | https://api.dc.library.northwestern.edu/api/v2 | Base URL for the Digital Collections API |
DC_IIIF_BASE | https://iiif.dc.library.northwestern.edu/iiif/3 | Base URL for the IIIF server |
SECRETS_PATH | _(none)_ | Base path for AWS Secrets Manager config |
bun run stdio
Or via the wrapper script (activates the correct Node.js version via mise):
bin/run.sh
bun run http
{
"mcpServers": { "dc-api": { "command": "/path/to/dc-api-v2/mcp/bin/run.sh" } } }
Replace /path/to/dc-api-v2/mcp with the absolute path to this directory. Restart Claude Desktop after editing.
| Command | Result |
|---|---|
bun run test | Run the test suite |
bun test:watch | Run the test suite, watching for changes |
bun test:coverage | Run the test suite and calculate coverage |
bun test:record | Run the test suite against live data and record new fixtures |
MSW_MODE=live to run against live data.bun test:record records new fixtures (requires mitmproxy: pip install mitmproxy).
