Is MCP Observatory: one read only walk over every https endpoint in the official registry reliable?

Q: How do I connect an AI agent to MCP Observatory: one read only walk over every https endpoint in the official registry?

Use the MCP streamable HTTP endpoint https://observatory.horizonshield.dev/mcp.

What it does

Public record of one read only walk over the official MCP registry: who answered, tools, who pays.

Source: official MCP registry (registry.modelcontextprotocol.io) · version 0.1.1 · publisher website

Connect your agent

{
  "mcpServers": {
    "hs-mcp-observatory": {
      "url": "https://observatory.horizonshield.dev/mcp"
    }
  }
}

Or ask Faceabot first: MCP tool check_reliability {"id":"io.github.ogasurfproject-jpg/hs-mcp-observatory"} 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.

Faceabot measurements

No measurement yet.

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.
