## 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 2026-10-04.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - 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.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 77/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 333 tokens (~83/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

- [cosmetic] “search_objectives” reworded the description of “region”

### 2026-10-02 (score 76, +1)

No change was recorded against any check on this day. Stability & Change Management went from 13 to 17. That category is still filling its 30-day observation window: 4 days of observed history at the previous scan, 5 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-09-30 (score 75, +1)

No change was recorded against any check on this day. Stability & Change Management went from 7 to 10. That category is still filling its 30-day observation window: 2 days of observed history at the previous scan, 3 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-09-28 (score 74, 0)

- [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server

### 2026-09-27 (score 74)

## MCP tools (4)

### `get_forecast_accuracy` (~60 tokens)

Forecast accuracy

Returns stored public regional forecast accuracy, including observed-station or model-proxy truth lineage, data sufficiency, and eligibility. Informational only.

Input parameters:

- `region_id` (string, required): Public accuracy region identifier, for example pnw-olympics.

### `get_objective_conditions` (~68 tokens)

Objective conditions

Returns public conditions for a covered objective: summit weather, source provenance, and timestamps, in JSON or markdown. Informational only.

Input parameters:

- `format` (string): Text representation; structured data is included in either format.
- `slug` (string, required): Public objective slug returned by search_objectives.

### `get_route_conditions` (~83 tokens)

Route conditions

Returns seven days of public route conditions, anchored to the route high point and aspect, with source provenance and timestamps. Informational only.

Input parameters:

- `format` (string): Text representation; structured data is included in either format.
- `route_id` (string, required): Route identifier returned by search_objectives.
- `slug` (string, required): Public objective slug returned by search_objectives.

### `search_objectives` (~122 tokens)

Search covered objectives

Searches the public coverage catalog by name or alias, with optional region and activity filters. Coverage follows the current public scope; region filters include WA, OR, and BC. Informational only.

Input parameters:

- `activity` (string): Optional visible activity filter.
- `limit` (integer): Maximum number of matching objectives.
- `query` (string, required): Objective name or alias; matching ignores case and accents.
- `region` (string): Optional state or province code or name: WA, Washington, OR, Oregon, BC, British Columbia, or B.C. Matching ignores case.

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

ClimbCast scores 77 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 ClimbCast MCP server expose?

ClimbCast exposes 4 tools: get_forecast_accuracy, get_objective_conditions, get_route_conditions, search_objectives. Their descriptions and schemas cost roughly 333 tokens of context every time the server is loaded.

### Does the ClimbCast MCP server require authentication?

No. We connected to ClimbCast without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the ClimbCast MCP server still maintained?

ClimbCast is still listed as active in the MCP registry. We last reached this channel on 4 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
