SolSigs MCP Server

AI Agent Gateway to Solana blockchain data via x402 micropayments.

What is this?

SolSigs MCP is a Model Context Protocol server that gives AI agents access to 22 Solana on-chain data tools — DEX prices, arbitrage scanning, wallet intel, token launches, AI market summaries, prediction markets, perps data, memecoin trenches, and more.

Each tool costs fractions of a cent USDC via the x402 protocol. No key required — start with 50 free calls automatically.

Quick Start

Free tier (no key needed):

pip install solsigs-mcp
solsigs-mcp
# → SolSigs MCP Server starting (stdio) [FREE-TIER MODE]...
#   50 free calls per session. Set SOLSIGS_MCP_KEY for paid mode.

Paid mode (unlimited calls):

pip install solsigs-mcp
export SOLSIGS_MCP_KEY="<your-base58-solana-private-key>"
solsigs-mcp
