## 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 2026-10-18.

- **Endpoint Security**: 63/100
  - 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 62/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 6266 tokens (~189/item across 33 items; 33 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 33 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 34 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.

### `nrfa_station_info` (~142 tokens)

Get NRFA gauging-station metadata, river, location and catchment area to identify a historical flow record. Supply the numeric NRFA station_id; use nrfa_get_timeseries for observations. Returns source data and provenance; supported hydrological units are normalised to SI. TerraMCP is a Wrench AI service. Open data: no API key or signup required. Anonymous limits: 60 calls/hour and 300/day per IP and session; keys offer higher limits, with anonymous fallback after monthly quota. Source licence warnings apply.

Input parameters:

- `station_id` (integer, required): Positive numeric NRFA gauging-station identifier; not an EA station ID.

### `nrfa_get_timeseries` (~250 tokens)

Get NRFA daily flow or catchment rainfall observations for historical catchment analysis. Use a numeric NRFA station_id, data_type gdf (gauged flow), ndf (naturalised flow) or cdr (catchment rainfall), and ordered YYYY-MM-DD dates at most 366 days apart. Returns source data and provenance; supported hydrological units are normalised to SI. TerraMCP is a Wrench AI service. Open data: no API key or signup required. Anonymous limits: 60 calls/hour and 300/day per IP and session; keys offer higher limits, with anonymous fallback after monthly quota. Source licence warnings apply.

Input parameters:

- `data_type` (string): NRFA series: gdf gauged daily flow, ndf naturalised daily flow, cdr catchment daily rainfall.
- `end` (string, required): End date in YYYY-MM-DD; must be no earlier than start, at most 366 days apart.
- `start` (string, required): Start date in YYYY-MM-DD; must be no later than end, at most 366 days apart.
- `station_id` (integer, required): Positive numeric NRFA gauging-station identifier; not an EA station ID.

### `usgs_daily` (~249 tokens)

Get USGS daily mean discharge, stage or water temperature for historical US monitoring analysis. Supply site_id (optional USGS- prefix), parameter_code 00060 (discharge), 00065 (stage) or 00010 (temperature), and ordered YYYY-MM-DD dates at most 366 days apart. Returns source data and provenance; supported hydrological units are normalised to SI. TerraMCP is a Wrench AI service. Open data: no API key or signup required. Anonymous limits: 60 calls/hour and 300/day per IP and session; keys offer higher limits, with anonymous fallback after monthly quota. Source licence warnings apply.

Input parameters:

- `end` (string, required): End date in YYYY-MM-DD; must be no earlier than start, at most 366 days apart.
- `parameter_code` (string): USGS parameter: 00060 discharge, 00065 stage, 00010 water temperature; daily mean.
- `site_id` (string, required): USGS monitoring location number (8–15 digits), optionally prefixed USGS-.
- `start` (string, required): Start date in YYYY-MM-DD; must be no later than end, at most 366 days apart.

### `dem_clip` (~182 tokens)

Get a bounded elevation GeoTIFF from OpenTopography for terrain analysis where an appropriate local DEM is unavailable. Supply WGS84 bbox [west,south,east,north] covering at most 100 km² and dataset; UK projects should prefer Defra 1 m LiDAR DTM. BYO OpenTopography key only; commercial use requires an OpenTopography Enterprise key. Returns source data and provenance; supported hydrological units are normalised to SI. TerraMCP is a Wrench AI service. Requires a TerraMCP Bearer key from https://terramcp.earth/account and your own OpenTopography key.

Input parameters:

- `bbox` (array, required): WGS84 bounds [west, south, east, north], ordered and covering at most 100 km².
- `dataset` (string): Dataset identifier from the allowed values in this schema.

## Common questions

### What is the TerraMCP MCP server?

TerraMCP is an MCP server listed in the public MCP registry as earth.terramcp/terramcp. A Wrench AI service for environmental source discovery and live UK open-data tools. This page covers its hosted endpoint (https://terramcp.earth/mcp).

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

TerraMCP scores 65 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 TerraMCP MCP server expose?

TerraMCP exposes 33 tools: search_sources, get_source, list_categories, top_sources, get_consultant, and 28 more. Their descriptions and schemas cost roughly 6,136 tokens of context every time the server is loaded.

### Does the TerraMCP MCP server require authentication?

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

### Is the TerraMCP MCP server still maintained?

TerraMCP is still listed as active in the MCP registry. We last reached this channel on 18 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
