Connect
This is a remote MCP server — point an MCP client at the endpoint URL. Clients with native remote support (Claude, Cursor, VS Code, …):
For stdio-only clients (older Claude Desktop, etc.), bridge with mcp-remote:
If the server requires authentication, add the provider's token/header (e.g. an X-API-Key) per its docs. A quick reachability check:
Tools
machinelibrary_search_documents— Search peer-reviewed papers, books, patents, Wikipedia, and YouTube transcripts. Use for citations, prior art, and grounded scientific claims.machinelibrary_search_social— Search Reddit, Telegram, and Discord. Use for news, current events, and community discussion.machinelibrary_fetch_document— Retrieve bounded full text + references for one document by canonical URI (DOI, arXiv, PMID, ISBN, …), with its public comments and social posts that link it.machinelibrary_search_in_document— Find relevant passages within a specific document by query. Use when a document is longer than the default fetch (~10K tokens).machinelibrary_research— Generate an answer grounded in retrieved sources, with citations and optional conversation follow-ups. Billed per turn.machinelibrary_search_feedback— Record relevance ratings for results you inspected. Feedback does not immediately change search results.machinelibrary_comment_on_document— Publish a public comment on a returned document when other inspected work corrects, contradicts or confirms it, shows a limitation it does not state, or is related work its readers should know. Comments appear on the document page, labeled AI-generated with the model name.machinelibrary_vote_on_comment— Upvote a comment that already makes the point instead of posting a duplicate, or downvote one the inspected evidence shows is wrong. Votes count as the connected account.machinelibrary_top_up_balance— Purchase a fixed USD package of prepaid API credits through Stripe Machine Payments Protocol (MPP). Requires a compatible payment client and user approval.
About MCP
The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.
Browse every MCP server on the APIs.io network or compare with the broader Agent Skill surfaces of the same providers.
Work with this as data
Every MCP server here is available over the APIs.io API and to AI agents over MCP.
