DexSheet MCP server

Give your AI assistant DexSheet's fee sheets. The server is free, public, read-only and needs no API key. It exposes the same dated, sourced data as /fees.json as four tools, so an agent can find a trading venue, read its full sheet, or rank venues by what a trade costs.

Endpoint

https://dexsheet.com/mcp

Transport: Streamable HTTP, stateless. Send JSON-RPC 2.0 messages (single or batched) with POST. Responses are application/json. CORS is open.

Tools

• search_venues: search by text, with optional category, chain, us_available and limit (max 25) filters.
• get_venue: the full record for a slug: fee components and tiers, perps fees, referral terms, custody, KYC, geo availability, status, sources.
• compare_fees: platform-fee cost in USD of a buy plus sell round trip at size_usd, cheapest first. Filter by slugs or category. Applies published referral discounts unless apply_referral_discount is false. Perp DEXs return taker and maker fees. Network fees, pool fees and slippage are excluded.
• list_categories: every category with its venue count.

Every venue result includes url (its DexSheet page) and open_url (a DexSheet link to the venue). open_url may resolve to a referral link that pays DexSheet a share of fees. Rankings and numbers never depend on referrals; see the disclosure and methodology.

Cursor

Add this to ~/.cursor/mcp.json (or the project's .cursor/mcp.json):

{
  "mcpServers": {
    "dexsheet": {
      "url": "https://dexsheet.com/mcp"
    }
  }
}

curl

curl -s https://dexsheet.com/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"curl","version":"0"}}}'

Then call a tool, for example the cheapest terminals for a $1,000 trade:

curl -s https://dexsheet.com/mcp \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"compare_fees","arguments":{"size_usd":1000,"category":"terminal"}}}'

Notes

• Data is regenerated with each site deploy. Each record carries a source URL and a checked_on date; the venue's own page wins if it disagrees.
• Tool failures return a result with isError: true. Protocol failures return standard JSON-RPC errors.
• Not financial advice. Coins traded on any venue can go to zero.
