What it does

First-Call Witness is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

No capability identified yet from its description.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.

Live check

Electra Index connected to the hosted endpoint 1h ago

ONLINE First-Call Witness answered an MCP connection on 23 Oct 2026 and introduced itself as first-call-latency-witness 1.0.0 (MCP protocol 2025-03-26).

3 tools offered to AI assistants

  • budgets · Get the versioned budget table
  • witness_check · Witness check — paid work is refused over MCP; payments collect on the HTTP x402 surface (POST /check)
  • verify_receipt · Verify a signed receipt envelope

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. $9.99/month.
