An MCP server providing public plant bioinformatics APIs including UniProt, NCBI, InterProScan, PDB, AlphaFold, Ensembl Plants, and web-based resources like Sol Genomics and BAR, without local data. It supports gene lookups, protein summaries, structure retrieval, and functional annotations through natural language.

e-yearbook.com MCP (Model Context Protocol) server. The server lets any MCP-aware AI agent search over 300,000 U.S. yearbooks indexed by name. Over 22,000 schools across all 50 U.S. states and territories Over 300,000 distinct (school, year) yearbooks Over 100M extracted person mentions

Enables AI agents to directly manipulate Jupyter Notebook cells and structure through a secure, well-defined API, overcoming Cursor's AI agent mode limitations.

Enables AI assistants to issue a single unauthenticated GET against an OpenAI-compatible endpoint and learn whether it publicly discloses model prices, returning a verdict plus entry and priced-item counts. It also lets the assistant read archived daily cross-provider readings for a given date.

Enables querying, sampling, and exporting datasets from over twenty keyless free public data sources spanning the EU, Switzerland, Germany, the US, and global providers through one uniform set of tools.
