Curo MCP connects your AI to peptide research and to Curo (https://curo.you). Add it to Claude, ChatGPT, Gemini, Grok, Perplexity or another MCP app. Your AI can then answer peptide questions from PepBank (https://pepbank.io), a free peptide research database, with study summaries, findings and a link to each source. It can also look up peptides in the Curo catalog (https://curo.you/product-catalog), with the third-party lab report for each lot (https://curo.you/coa), prices, stock and shipping. Server address: https://mcp.curo.you. Setup guide: https://curo.you/mcp.
Database schema inference, dialect normalization, query plan optimization, and SQL audit over streamable HTTP.
A portable knowledge-graph memory you pass in and get back. No database. 4 of 6 free.
Patchwire is a free, read-only MCP server for security advisories on modern JS, AI and web3 stacks. It reads maintainers' own advisories and vendor security posts every hour, often days before they reach the GitHub Advisory Database, and returns vulnerable ranges, fixed versions per release line and the conditions that make each flaw exploitable. Send package names, never versions. No account, no key.
Data Oil is a multi-model database built for object storage. It uses a log-structured storage engine, snapshot isolation with optimistic commit, and a change feed from the write-ahead log. Its SQL dialect supports joins, window functions, CTEs, set operations, graph traversal and pattern matching. It has its own HNSW vector index and BM25 full-text index, and a write is searchable by keyword and vector as soon as it commits. Access is over HTTP, the PostgreSQL wire protocol (extended protocol). We have a founder's program available for projects which may be of interest https://dataoil.tech/founders.html if your interested lets chat ;)

CWI Discovery Engine is the sync-licensing discovery layer for AI agents: natural-language brief in, licensable tracks with verified ISRCs and one-signature clearance out. 29 MCP tools (find_tracks_for_brief leads). For general ISRC metadata lookup, we defer to MusicBrainz — we are the licensable-track discovery layer, not a general database.
