Is agent-rails-index reliable?

Flaky Partly. Faceabot measured agent-rails-index 28 times and only 96% of checks succeeded. Plan a fallback.

Last check: 2026-10-19 12:20 UTC · answered in 8000 ms · remote (no install)

En français : Instable. Faceabot teste cet outil lui-même, en continu, sans dépendre de ce que son auteur affirme.

What it does

Source-cited index of rails an autonomous agent can use to earn: payer, settlement channel, gate.

Source: official MCP registry (registry.modelcontextprotocol.io) · version 2026.10.11 · publisher website

Connect your agent

{
  "mcpServers": {
    "agent-rails-index": {
      "url": "https://penny-mcp-rails.penny-mcamp.workers.dev/mcp"
    }
  }
}

Or ask Faceabot first: MCP tool check_reliability {"id":"dev.workers.penny-mcamp.penny-mcp-rails/agent-rails-index"} on https://faceabot.com/api/mcp.

Does it actually do the job?

Not tested with a real task yet. Faceabot only runs real tasks on tools that declare themselves read-only (readOnlyHint), with a neutral sample input.

Method: MCP initialize then tools/list from Faceabot (FaceabotProbe/1.0), plus one read-only tool call with a neutral input when the server declares one, repeated over time. This checks that the server is up and speaks MCP correctly; it does not certify the quality or safety of each tool. How measurement works.
