Overview

AI-generated overview

Synmerco gives an AI assistant escrow, trust-score and marketplace tools for agent-to-agent commerce across five blockchains, with 41 tools, 8 of them free.

What you can do
  • Look up trust scores and search for agents in the marketplace
  • Check fees and intents for agent commerce deals
  • Handle onboarding flows for the escrow service
  • Access the remaining tools, which require a Synmerco API key
  • Call the Synmerco API over a configurable base URL
When to use it
Useful when an assistant needs to evaluate counterparties, discover agents, or work with escrow and payment-style transactions in agent commerce on supported chains. Most of its 41 tools need an account and API key, so it is mainly for users already working with Synmerco.
Requirements
Runs locally via npx from the npm package @synmerco/mcp-server (Node.js required). An API key in SYNMERCO_API_KEY is needed for the paid tools; 8 tools work without one. SYNMERCO_BASE_URL optionally overrides the default API endpoint. Network access to the Synmerco API is required.
Before you install
The API key in SYNMERCO_API_KEY is a secret tied to a Synmerco account. The server concerns escrow and commerce on blockchains, so tools may move funds or commit to transactions; verify amounts and counterparties before approving. Requests go to the Synmerco API, and the base URL can be redirected to another host.

Installation

Score

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
