Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog) Scored 2026-09-20. - **Supply Chain Security**: 0/100 - Malware scan not yet available for this package. - Known CVEs could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it. - Install-script risk not yet assessed. - Dependency health could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it. - **Provenance & Transparency**: 32/100 - Source repository is publicly reachable at the declared URL. - Provenance check failed: no build-provenance attestation is published. - License check failed: the license (NOASSERTION) isn't a recognized OSI-approved license. - Actively maintained (last published 14 days ago). - Disclosure check failed: no security disclosure policy was found in the source repository. - **Schema Quality & AI Usability**: 84/100 - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name). - AI-judged instruction clarity (good). - Tool/resource definitions use about 746 tokens (~82/item across 9 items; 8 tools + 1 resources), lean. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 0/100 - Stability not yet verified: not enough scan history yet (needs a 30-day window). - **Tool Coverage**: 100/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 100% of tool parameters carry a description. - Structured output schemas are declared (88% of tools); any adoption earns full credit. - **Tool Safety**: 100/100 - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured. - We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation. - An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it. - **Capabilities**: 100/100 - Implements a current MCP spec version (2026-07-28). - Supports UI / widget rendering. **Unverified: 2 categories.** Categories scored 0 because we could not verify them: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm. ## Install ### How do I install the Northwestern University Libraries Digital Collections API MCP server?

Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims. ### 2026-09-15 (score 40) First indexed and scored. ## MCP tools (8) ### `search` (~245 tokens) Search Search for works in the Digital Collections using field-based and/or natural language queries. If both a natural language query and specific field values are provided, the natural language query will take priority, using the specified field values as additional constraints. The result will also include a list of aggregations that show how many results match different values for certain fields. For example, you could see how many results match each collection, work type, or visibility and use that information to refine your search. Perform an empty search to retrieve all works and their aggregations. NOTE: Structured field values enclosed in double quotes will be treated as exact, case-sensitive matches, while unquoted values will be treated as full-text searches. Input parameters: - `fields` (object): Structured field search. Best when searching for specific known items or values, or for narrowing a search by specifying particular fields to search within. - `max_results` (number): The maximum number of search results to return per page - `page` (number): The page of search results to return - `public_only` (boolean): Only include publicly available works in search results - `query` (string): A natural language query. Best for exploratory / conceptual searches. Output parameters: - `aggregations` - `data` (array): The search results returned from the Digital Collections API - `explain`: The explain output from Elasticsearch for the search query. Only included if the MCP is running in debug mode. - `info` (object) - `pagination` (object) ### `get-work` (~37 tokens) Get Work Retrieve the full metadata for a work from the NUL Digital Collections. Input parameters: - `work_id` (string, required): The ID of the work to retrieve ### `list-collections` (~67 tokens) List Collections List collection records from the NUL Digital Collections.

Northwestern University Libraries Digital Collections API is an MCP server listed in the public MCP registry as io.github.nulib/dc-api. Agent integration with the Northwestern University Libraries Digital Collections API. This page covers its container image (ghcr.io/nulib/dc-api-mcp:2.11.15). ### Is the Northwestern University Libraries Digital Collections API MCP server safe to use? Northwestern University Libraries Digital Collections API scores 40 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm. ### What tools does the Northwestern University Libraries Digital Collections API MCP server expose? Northwestern University Libraries Digital Collections API exposes 8 tools: search, get-work, list-collections, similarity-search, view-work, and 3 more. Their descriptions and schemas cost roughly 725 tokens of context every time the server is loaded. ### Is the Northwestern University Libraries Digital Collections API MCP server still maintained? Northwestern University Libraries Digital Collections API is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced. ### What licence is the Northwestern University Libraries Digital Collections API MCP server under? Northwestern University Libraries Digital Collections API declares the NOASSERTION licence, which is not on the OSI-approved list. Read the terms before using it at work, and note this covers the source only, not the cost of any service it calls. ## Links - Repository: https://github.com/nulib/dc-api-v2 - Changelog RSS feed: https://verifymcp.io/servers/nulib-dc-api/ghcr-io-nulib-dc-api-mcp-2-11-15.xml - Changelog JSON feed: https://verifymcp.io/servers/nulib-dc-api/ghcr-io-nulib-dc-api-mcp-2-11-15.json - HTML version of this page: https://verifymcp.io/servers/nulib-dc-api/ghcr-io-nulib-dc-api-mcp-2-11-15
