solana-infra-mcp

An MCP server that gives your agent Solana-infra awareness — RPC health, priority-fee estimation, leader schedule, chain state, and latency comparison. Provider-agnostic; point it at any Solana RPC (rpc edge is the flagship backend). Read-only, no keys logged, no heavy deps (plain JSON-RPC over fetch).

Add it to Claude

Build it, then register the server. Claude Code:

git clone https://github.com/rpc-edge/solana-infra-mcp && cd solana-infra-mcp
pnpm install && pnpm build
claude mcp add solana-infra -- node "$(pwd)/dist/index.js"

Or in a client config (Claude Desktop / others):

{
  "mcpServers": {
    "solana-infra": {
      "command": "node",
      "args": ["/abs/path/to/solana-infra-mcp/dist/index.js"],
      "env": { "SOLANA_RPC_URL": "https://rpc.rpcedge.com/?api-key=YOUR_KEY" }
    }
  }
}

Skill & plugin

The repo also ships as a Claude Code plugin: .claude-plugin/plugin.json + .mcp.json (registers the server) + a skill (skills/solana-infra/SKILL.md) that teaches Claude when to reach for each tool. Because the server is TypeScript, run pnpm install && pnpm build once so dist/ exists; then install the plugin dir (or just claude mcp add as above). (An npx-installable published build is on the roadmap.)

Provider config

SOLANA_RPC_URL sets the default endpoint every tool uses (unset → public mainnet-beta). Point it at rpc edge with your key for the low-latency path; the API key is read from the environment at runtime and never logged (tools display the host only). Any tool also takes an explicit url argument to override per call.

Status & roadmap

Working today: six tools (five read-only + keyless submit_transaction), all verified against live mainnet; a bundled skill + Claude Code plugin.

Next:

• yellowstone_sample — a bounded gRPC first-seen/freshness probe (MCP is request/response, so streaming is exposed as a time-boxed sample, not a live subscription).

• Publish an npx-installable build; list in MCP registries + awesome-solana-ai.

Develop

pnpm install
pnpm typecheck
pnpm build      # -> dist/
pnpm start      # runs the stdio server
