**An agent can connect right now, no human step.** Remote endpoint, no authentication, reachable on the last probe.

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "flop-independent-verification": {
      "type": "http",
      "url": "https://opti.tailbdecdd.ts.net/mcp"
    }
  }
}
```


## Trust

- hygiene: 100
- liveness: 100
- freshness: 100
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-100% +updated-8d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 79/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 1 of 1 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 94 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 25 (weight 15)

- warn `stability.changes`: 7 tool changes in 30 days
- fail `stability.rug_pull`: 1 tools kept their name but changed most of their description in 30 days; review before trusting them

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 1, about 94 tokens to load them all
- tool set hash: 9fd8b4ae36eecd647da4ed283e36fba1
- tools last changed: 2026-10-13T11:15:42.444Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.ninjatrader542/flop-independent-verification.svg)](https://protogrid.dev/servers/io.github.ninjatrader542/flop-independent-verification)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-13 `a2a_agent_card_verify` removed
  - Read one public HTTPS Agent Card; verify pinned A2A format, endpoint and optional DID JWS. No Task.
- 2026-10-13 `provenance_verify` removed
  - Check supplied Sources V2 or Artifact provenance against supplied evidence; no fetch.
- 2026-10-13 `json_schema_validate` removed
  - Validate a JSON value against a bounded JSON Schema without network references.
- 2026-10-13 `artifact_verify` removed
  - Verify an A2A Artifact, signed FLOP descriptor or supplied V1/V2 bundle; no publication.
- 2026-10-13 `tclk_transcript_audit` removed
  - Audit a bounded TCLK transcript with the installed official TCLK package.
- 2026-10-13 `public_github_commit_verify` removed
  - Verify a public GitHub commit SHA and expected changed paths.
- 2026-10-13 `hash_verify` changed (description, inputSchema, outputSchema, annotations) **meaning changed**
  - before: Fetch a bounded public HTTPS resource and compare its SHA-256 digest.
  - after: Compare the SHA256 of bounded UTF-8 data with an exact lowercase hash.
