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. How we score → Why this is hard to score →
Endpoint Security63
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability64
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 741 tokens (~247/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage71
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the NOAA Climate Data MCP server?
NOAA Climate Data is a hosted endpoint at https://mcp.olyport.com/noaa-climate/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.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
find_stations ~168
Find NOAA weather stations in an area. Returns a list of weather stations with their IDs, names, coordinates, and active date ranges. Use the station IDs with get_climate_data. Args: state: Two-letter US state abbreviation (e.g. 'CA', 'NY'). county_fips: Five-digit county FIPS code (e.g. '36061' for Manhattan). dataset: Dataset ID to filter stations that have data in this dataset. Default is 'GHCND' (daily summaries). limit: Maximum number of stations to return (default 25, max 1000).

get_climate_data ~347
Get climate observations from NOAA Climate Data Online. Returns historical weather measurements such as temperature, precipitation, and snowfall. You must provide either a station_id or a FIPS code to identify the location, and a date range. Args: station_id: NOAA station identifier (e.g. 'GHCND:USW00094728' for Central Park). fips: FIPS code for county or state (e.g. '36' for New York state, '36061' for Manhattan). dataset: Dataset ID. Common values: 'GHCND' (daily summaries), 'GSOM' (monthly), 'GSOY' (annual), 'NORMAL_DLY' (daily normals). Default is 'GHCND'. start_date: Start date in YYYY-MM-DD format. Required for most datasets. end_date: End date in YYYY-MM-DD format. Required for most datasets. data_types: Comma-separated data type IDs to filter. Common types: TMAX (max temp), TMIN (min temp), TAVG (avg temp), PRCP (precipitation), SNOW (snowfall), SNWD (snow depth), AWND (avg wind speed). If omitted, all available types are returned. limit: Maximum number of records to return (default 100, max 1000).

get_climate_normals ~226
Get 30-year climate normal values for a NOAA weather station. Climate normals are averages computed over the most recent 30-year period (currently 1991-2020). They represent typical conditions for a location and are useful for comparing current conditions to historical baselines. Args: station_id: NOAA station identifier (e.g. 'GHCND:USW00094728'). Use find_stations to look up station IDs. data_types: Comma-separated normal data type IDs to filter. Common types: DLY-TMAX-NORMAL (avg daily max temp), DLY-TMIN-NORMAL (avg daily min temp), DLY-TAVG-NORMAL (avg daily temp), DLY-PRCP-PCTALL-GE001HI (precip probability), MTD-PRCP-NORMAL (monthly precip), ANN-TMAX-NORMAL (annual max temp).

Is the NOAA Climate Data MCP server safe to use?
NOAA Climate Data scores 76 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 NOAA Climate Data MCP server expose?
NOAA Climate Data exposes 3 tools: get_climate_data, find_stations, get_climate_normals. Their descriptions and schemas cost roughly 741 tokens of context every time the server is loaded.
Does the NOAA Climate Data MCP server require authentication?
No. We connected to NOAA Climate Data without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the NOAA Climate Data MCP server still maintained?
NOAA Climate Data is still listed as active in the MCP registry. We last reached this channel on 24 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
