Official Solana MCP Server

Overview

The Solana Foundation runs this MCP server to give AI agents and IDEs up-to-date Solana developer documentation through semantic RAG search, section retrieval, and a program autofixer that checks Anchor/Pinocchio Rust code. It's hosted at mcp.solana.com over Streamable HTTP and can also run locally via Node.js. Builders plug it in as a documentation and code-review layer for Solana program development.

Tool inventory — 5 tools, probed live 2026-08-30

• Solana_Expert__Ask_For_Help — Ask a Solana expert (RAG over docs). Use for narrow how-to / debugging Qs; prefer get_documentation for full canonical docs.
• Solana_Documentation_Search — Semantic search over the Solana docs corpus (RAG). Use for narrow queries; prefer get_documentation for full canonical docs.
• list_sections — Lists Solana doc sources tagged by section + use_cases. Call before get_documentation to pick relevant ids.
• get_documentation — Fetch full docs for source id(s) or section id(s). Token-intensive — pick from list_sections first; prefer Solana_Documentation_Search for narrow questions.
• program_autofixer — Static security linter for Solana program Rust (Pinocchio + Anchor). Returns issues (with stable `fingerprint`), suggestions, detected framework, `false_positive_hints` (rule → known blind spots), and
