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 ;)
