About peptides.farm
peptides.farm is a hosted reference server for peptide data, aimed at applications that need structured, cited information on studies, safety, and regulatory status. It also provides paid JSON endpoints, with x402 payments and API-key access.
Key features
- 01Peptide snapshots and citations
- 02Clinical and preclinical trial data
- 03Safety and regulatory details
- 04Cited search and comparisons
- 05JSON API with x402 payments
Use cases
- 01Check sources behind peptide information
- 02Review reported trials and regimens
- 03Compare two to five peptides
- 04Retrieve structured data through an API
MCP support
The hosted MCP server is available at `https://peptides.farm/mcp` over Streamable HTTP. Its tools mirror the API endpoints; paid calls can be retried with x402 payment metadata or made with an API key.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
