Claude Code Synap synap_estimate_cost

How to: Claude Code Synap synap_estimate_cost

client:Claude Code transport:streamable-http tool:synap_estimate_cost

Add Synap to Claude Code

  1. 01

    Run this in your project directory.

claude mcp add --transport http synap-mcp https://synap402.com/mcp
  1. 02

    Restart your session so the server is picked up.

  2. 03

    Ask for something synap_estimate_cost does. Claude Code lists the server's tools on connect and calls synap_estimate_cost itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Synap's identifier in your config matches the one above exactly.

Adds it for this project only. Append --scope user to make it available everywhere. Claude Code docs

Set these first

Synap will not start until these are set, so synap_estimate_cost never becomes available.

  • SYNAP_API_KEY
  • SYNAP_WALLET_KEY
  • SYNAP_SOLANA_KEY
  • SYNAP_MAX_PER_CALL_USD

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 8 November 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
