## 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 2026-09-20.

- **Endpoint Security**: 94/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
  - The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 60/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1222 tokens (~203/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 57/100
  - Stability observed for 17 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (6)

### `search_entities` (~36 tokens)

Search entities

Find tracked entities (repositories, packages, companies) by name substring.

Input parameters:

- `limit` (integer)
- `q` (string, required)

### `get_entity` (~138 tokens)

Get entity

One entity's public record: identity, the day it was last velocity-scored, 30-day metric history, and every live question about it with its latest forecast. Every FIGURE in the velocity block — `composite`, `layer_scores` and the `stage` label — is withheld (null, with a `withheld` sibling saying why), so do not report a velocity number and do not describe the project as emerging or fading on our behalf. A velocity block that is present with null figures means we scored the entity and withheld the result; a velocity of null means we never scored it.

Input parameters:

- `entity_id` (integer, required)

### `get_question` (~32 tokens)

Get question

One question with every live forecast ever issued for it and its resolution if settled.

Input parameters:

- `question_id` (integer, required)

### `list_forecasts` (~38 tokens)

List forecasts

The public forecast log: newest live forecasts across all entities, with titles.

Input parameters:

- `limit` (integer)
- `offset` (integer)

### `get_calibration` (~509 tokens)

Get calibration record

The calibration record: Brier skill by question family for the pastcast pool and the live track, with the launch-gate verdict for the horizon asked for. horizon: 7, 30, 90, long, or all (default: the horizon the latest verdict scopes on); the 90-day maintenance families (commits_90d, release_90d) are at 90. regime.gate is the verdict evaluated on THAT horizon, or null when no gate has been run on it — never another horizon's verdict, so null means those families are unjudged, not that they failed. regime.latest_gate is the newest verdict overall whatever its horizon, carrying its own domain and horizon_days; read applies_to_this_view before treating it as a verdict on the families returned. SHAPE: `pastcast` and `live` each carry the track's own statistics plus `families`, a list of per-family blocks (family, label, n, brier, brier_skill_score, base_rate, mean_p, z_bias, hit_rate, bins, enough_to_judge). Every one of those blocks, and each track, also carries a `withheld` sibling: null when the numbers are real, otherwise an object {reason, metrics, degraded_from, detail}. WHEN `withheld` IS NON-NULL, EVERY NUMBER IN THAT BLOCK IS JSON null — n included. null there means 'we refuse to publish this', NOT zero and NOT 'nothing resolved'; do not coerce it to 0, do not average over it, and do not report it as a score. A real n=0 with `withheld: null` is the honest 'nothing has resolved yet'. The families over GH Archive activity series — commits_90d, release_90d and the legacy daily families commits_hourly, release_published and stars_hourly — are withheld unconditionally today, with reason 'resolutions_untrusted': every one of those questions was resolved by counting a GH Archive series whose capture collapsed, so no score over that pool is sound at any horizon. `detail` is a sentence you can quote to the user. Other reasons a number can be withheld are 'source_degraded', 'source_collapsed' and 'insufficient_data'. Every other family (news tone, Wikipedia pageviews, H…

Input parameters:

- `horizon`

### `dependency_risk` (~368 tokens)

Dependency risk

Calibrated, timestamped maintenance-risk forecast for an open-source package or GitHub repository, for choosing or auditing a dependency. Pass an npm, PyPI or crates.io package name, a GitHub owner/repo or URL, or a prefixed name (npm:express, pypi:requests, crate:serde, repo:owner/name). Returns the latest open forecasts that the repository keeps its commit pace (commits_90d) and ships a release (release_90d) in the next 90 days — each with its question id, probability, issue time and resolution date; 90 days of commit, release and star activity summarised (commits last 30 vs prior 30 days, days since last commit and last release, releases in the last year); a velocity block that now carries only the day the entity was last scored — both the `composite` score and the `stage` label are withheld, arriving as null with a `withheld` sibling naming them, and they are not figures we failed to compute, so do not describe a project's momentum on our behalf; plain-language signals derived from those numbers (e.g. 'no commits in 60 days', 'release cadence slowing'); and a calibration note with the family's resolved-forecast count and Brier score, or 'no track record yet'. A package is linked to its repository when the archive knows the link; repo_link says how (self, source_repo = the registry's recorded repository, external_ids, name_match = a labelled guess, unknown). Nothing is estimated on the fly: every number comes from the archive and the answer names what is missing. Not found = no tracked match; try the exact package name or owner/repo.

Input parameters:

- `query` (string, required)

## Common questions

### What is the Anteproof MCP server?

Anteproof is an MCP server listed in the public MCP registry as com.anteproof/anteproof. Dependency risk + calibrated, publicly scored forecasts on OSS packages. Docs: anteproof.com/docs. This page covers its hosted endpoint (https://api.anteproof.com/mcp).

### Is the Anteproof MCP server safe to use?

Anteproof scores 82 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 Anteproof MCP server expose?

Anteproof exposes 6 tools: search_entities, get_entity, get_question, list_forecasts, get_calibration, dependency_risk. Their descriptions and schemas cost roughly 1,121 tokens of context every time the server is loaded.

### Does the Anteproof MCP server require authentication?

Yes. Anteproof asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

### Is the Anteproof MCP server still maintained?

Anteproof is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
