It uses a plain API key, has no status page we could reach, and its terms weren't found. ## Facts | Field | Value | | --- | --- | | Vendor | Meteosource (https://www.meteosource.com) | | Kind | MCP server | | Category | Weather & climate data (https://www.anchorterminal.com/categories/weather) | | Transport | Streamable HTTP | | Endpoint | `https://mcp.meteosource.com/mcp` | | Auth | API key · A Meteosource API key in an Authorization: Bearer header (or X-API-Key). No OAuth. The key's plan decides which tools appear; the key is used only to call Meteosource and isn't stored in full. | | Pricing | Freemium ($9 / mo) · Free plan with 400 calls a day and no card, asking for a mention and backlink; Startup $9 a month (10,000 calls a day); Standard $29 a month; Renewables plan for production tools (checked 2026-11-07). | | x402 | No · No x402, MPP or L402 on the MCP docs or pricing page (checked 2026-11-07). | | Licence | Proprietary service.

Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. "This run" is each category's share of the 100 points. | Category | Weight | This run | Score (0–100) | Points | | --- | --- | --- | --- | --- | | Reliability | 16% | 20 | 35 | 7.0 | | Performance | 10% | pending | pending | n/a | | Schema & documentation | 13% | 16.2 | 72 | 11.7 | | Agent ergonomics | 13% | 16.2 | 75 | 12.2 | | Security & auth | 14% | 17.5 | 42 | 7.3 | | Payments & pricing | 10% | 12.5 | 30 | 3.8 | | Task success | 10% | pending | pending | n/a | | Maintenance & community | 7% | 8.8 | 70 | 6.1 | | Transparency & trust (editorial 25, provenance 38) | 7% | 8.8 | 32 | 2.8 | | Negative events | up to −15 | up to −15 | none recorded | 0 | | **Total** | | | | **50.9 → D** | ### Why each score - Reliability 35 (checked 2026-11-07): status.meteosource.com wasn't reachable (0). No history (5). Daily call quotas per plan, and the README's plans-and-limits section (15). Documented limits on request size (400 location-days) with what to do, no 429 guidance (5 of 15). No SLA found (0). Version 0.1.2, not labelled beta (10). 0 + 5 + 15 + 5 + 0 + 10 = 35. - Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes. - Schema & documentation 72 (checked 2026-11-07): Seven tools read from tools/list with JSON Schema inputs (25). No llms.txt found; the README is Markdown on GitHub (5 of 10). Descriptions say what each returns and which plan it needs (15 of 20). Typed inputs, no enums (10 of 15). A README table of error messages and fixes (10 of 15). Tagged releases v0.1.0 to v0.1.2, no changelog file (7 of 15). 25 + 5 + 15 + 10 + 10 + 7 = 72. - Agent ergonomics 75 (checked 2026-11-07): Seven tools, about 20 KB (25). Date ranges and location limits on history (12 of 20). Documented error messages with fixes (15 of 20). No annotations on the tools (8 of 20, all reads). Two values to connect and a cache per key; Meteosource SDKs not checked (15). 25 + 12 + 15 + 8 + 15 = 75. - Security & auth 42 (checked 2026-11-07): One API key per account in a header, never in the URL (20 of 30). All tools are reads (10 of 20). Weather data only, no third-party text (10). No audit log (0). No security programme found (2 of 20). Keys travel to the hosted server, which says it doesn't store them in full. 20 + 10 + 10 + 0 + 2 = 42. - Payments & pricing 30 (checked 2026-11-07): No machine payment protocol (0). Plan prices with daily call quotas, public (10). Free plan with 400 calls a day, no card (20). A person signs up in a browser for the key (0). 0 + 10 + 20 + 0 = 30. - Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored. - Maintenance & community 70 (checked 2026-11-07): Repository commit and tag v0.1.2 on 26 October 2026 (30). Three tags in 90 days (20). Repository issues not read (0). Official registry entry com.meteosource/weather (15). Small repository with server.json; server source not public (5 of 10). 30 + 20 + 0 + 15 + 5 = 70. Registry presence read from Anchor Terminal's own daily import of the official MCP registry (/api/v1/registry.json, 6 November 2026), not the registry's API. - Transparency & trust 32 (checked 2026-11-07): The repository is MIT (copyright 2026 Meteosource) but holds docs and the registry manifest rather than the server; terms and privacy URLs weren't found (10 of 30). The MCP page says keys aren't stored in full and caches are per key (10 of 30). No deprecation policy (0). Subprocessors not found (5 of 20). 10 + 10 + 0 + 5 = 25.

Not legal advice. **Terms of service**. We found no terms of service published for this product, so there is nothing to read and the check scores 0. **Privacy policy**. We found no privacy policy published for this product, so there is nothing to read and the check scores 0. ## Humans behind the project (researched 2026-11-07 from public pages, not part of the grade) ### Key people - No people named yet. - Note: People, ownership and investors weren't researched in this batch (7 November 2026, leads from the awesome-remote-mcp-servers pull requests). ### Getting support - Help: https://mcp.meteosource.com - Sources: https://mcp.meteosource.com ## Live (updated 2026-11-08 00:43 UTC) - Right now: up, HTTP 200, 193 ms, checked 2026-11-08 00:43 UTC (mcp-initialize on `https://mcp.meteosource.com/mcp`) - Uptime 24h 100.0% (61 probes) · 30 days 100.0% (61 probes) · p50 151 ms · p95 199 ms - Always current: https://www.anchorterminal.com/api/v1/live/meteosource-mcp.json ## Probe metrics Not measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score. ## Prices | Item | Price | Unit | Note | | --- | --- | --- | --- | | Startup plan | $9 | per month (plan) | 10,000 calls a day | | Standard plan | $29 | per month (plan) | 20,000 calls a day | Across all listings: https://www.anchorterminal.com/prices/index.md ## Strengths - Seven compact tools with plan requirements in the descriptions - Documented error messages with fixes - Forecasts, alerts, air quality, 20 years of history and solar and wind production - Free plan with 400 calls a day and no card - Official registry entry ## Weaknesses - Plain API key, no OAuth - No tool annotations - Status page unreachable and no incident history - Terms and privacy not found ## Before you call it (notes for agents) 1. Call search_places first to resolve a location 2. Split history requests over 400 location-days into shorter ranges 3. Production tools need the Renewables plan; check which tools the key exposes 4.

The badge or a plain link to this page verifies the listing, from a page on meteosource.com or one of its subdomains, or the README at the root of github.com/Meteosource/meteosource-weather-mcp. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{"slug": "meteosource-mcp", "url": "…"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp.
