## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-13.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not yet verified: we couldn't confirm whether this endpoint requires it.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS not yet verified: we couldn't read the response headers to check for it.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but we couldn't connect to verify it.
- **Schema Quality & AI Usability**: 0/100
  - Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Tool Safety**: 0/100
  - Tool safety not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Capabilities**: 0/100
  - Capabilities not yet verified: we couldn't read the endpoint's capabilities.

**Unverified: 5 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## Install

### How do I install the ProofRail MCP Release Certifier server?

ProofRail MCP Release Certifier is a hosted endpoint at https://drkdm4jd-8767.uks1.devtunnels.ms/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (8)

### `health` (~12 tokens)

ProofRail process health

### `proofrail_info` (~34 tokens)

FREE, read-only: ProofRail MCP verification, MCP server verification, compatibility preflight, certification capabilities, and payment mode

### `mcp_radar_snapshot` (~125 tokens)

MCP Radar Snapshot

FREE, read-only: inspect ProofRail's latest autonomous scan of public MCP endpoints discovered from public registries. This returns cached point-in-time results and does not trigger a live scan.

Input parameters:

- `connection` (string)
- `limit` (integer)
- `min_observations` (integer)
- `min_pass_rate` (number)
- `min_tools` (integer)
- `outcome` (string)
- `query` (string)
- `sort` (string)
- `source` (string)
- `tool_contains` (string)

### `find_mcp_servers` (~129 tokens)

Find MCP Servers

FREE, read-only: find currently reachable public MCP servers from ProofRail's autonomous catalog. Call with no arguments for the most stable current PASS/ok candidates, or provide query for task/capability search across names, URLs, repositories, and observed tool names. Returns optional x402 certification offers. Cached results only.

Input parameters:

- `limit` (integer)
- `min_observations` (integer)
- `min_pass_rate` (number)
- `min_tools` (integer)
- `query` (string)
- `sort` (string)
- `source` (string)

### `mcp_radar_changes` (~56 tokens)

MCP Radar Changes

FREE, read-only: inspect changes observed between ProofRail's two latest autonomous MCP Radar scans. Cached results only; this does not trigger a live scan.

Input parameters:

- `limit` (integer)
- `type` (string)

### `mcp_release_preflight` (~108 tokens)

Free MCP Endpoint Preflight

FREE, no payment: run an MCP server verification and compatibility preflight now for reachability, protocol negotiation, tool count, and schema issue count before buying a full evidence receipt.

Input parameters:

- `check_profile` (string): Verification profile; basic covers connection, protocol negotiation, tools/list, and schemas
- `declared_protocol_version` (string): MCP protocol version the target release claims to support
- `target_url` (string, required): Public MCP Streamable HTTP endpoint to certify before deployment or integration

### `quote_certification` (~70 tokens)

FREE, read-only, no arguments required for a general MCP verification/certification quote: get price and network before payment. Pass target_url to receive the exact buy_now action.

Input parameters:

- `check_profile` (string)
- `declared_protocol_version` (string)
- `target_url` (string)

### `mcp_release_certify` (~259 tokens)

Paid MCP server verification and certification with deployment contract checks: require named tools with required_tools, compare baseline_schema_hashes from a previous certification, and receive ALLOW/BLOCK/REVIEW evidence. Certification before deploy, upgrade, or trust. Returns deterministic PASS, FAIL, or PARTIAL evidence. Call with target_url; when payment is absent the x402 layer returns payment requirements/challenge, then the client pays and retries the same call. Use mcp_release_preflight first for a free no-payment compatibility check, or quote_certification(target_url) for an exact buy_now action.

Input parameters:

- `baseline_schema_hashes` (object): Paid drift check: prior contract_baseline; removed tools fail, changed input-schema hashes require review.
- `check_profile` (string): Verification profile; basic covers connection, protocol negotiation, tools/list, and schemas
- `declared_protocol_version` (string): MCP protocol version the target release claims to support
- `fixture_id` (string): Optional server-configured safe fixture id; callers cannot provide arbitrary tool arguments
- `required_tools` (array): Paid integration gate: fail if any named tool is missing.
- `target_url` (string, required): Public MCP Streamable HTTP endpoint to certify before deployment or integration

## Common questions

### What is the ProofRail MCP Release Certifier server?

ProofRail MCP Release Certifier is listed in the public MCP registry as io.github.kaattaallaa-sketch/proofrail. MCP deployment checks: required tools, schema drift and verifiable receipts. Free preflight. This page covers its hosted endpoint (https://drkdm4jd-8767.uks1.devtunnels.ms/mcp).

### Is the ProofRail MCP Release Certifier server safe to use?

ProofRail MCP Release Certifier scores 0 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the ProofRail MCP Release Certifier server expose?

ProofRail MCP Release Certifier exposes 8 tools: health, proofrail_info, mcp_radar_snapshot, find_mcp_servers, mcp_radar_changes, and 3 more. Their descriptions and schemas cost roughly 793 tokens of context every time the server is loaded.

### Does the ProofRail MCP Release Certifier server require authentication?

Its publisher declares no required credentials for ProofRail MCP Release Certifier. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

### Is the ProofRail MCP Release Certifier server still maintained?

ProofRail MCP Release Certifier has been unreachable for long enough that we treat it as dead, and its score is pinned to zero. We last reached this channel on 1 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
