The docs are eleven Markdown pages\n\n\n## Why the edge\n\n### Maintenance \u0026 community: Meteosource Weather MCP +55\n\n- Meteosource Weather MCP (70): 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.\n- Stormglass API (15): The latest dated announcement is the ERA5 blog post of 26 February 2026, 225 days before this check. The docs files carry a Last-Modified header of 29 June 2026, 102 days before, and the terms are dated 17 March 2026, so we scored the last visible change as within 180 days (10 of 30). No dated entry falls in the last 90 days (0 of 20). The blog announced new sources in May and September 2025 and twice in February 2026. Support is by email and comes with the Medium plan and higher, which we did not test (5 of 15). No official SDK was found (0 of 15). There is no public package or repository to assess (0 of 10).\n\n### Schema \u0026 documentation: Meteosource Weather MCP +32\n\n- Meteosource Weather MCP (72): 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.\n- Stormglass API (40): No OpenAPI file or other machine-readable contract was found in the docs (0 of 25). llms.txt returns 404. The docs site is Docsify, so each of its eleven pages is also a plain Markdown file, which is how we read them (5 of 10). Each endpoint page states its purpose, and the weather page points to the historical endpoint for past data and explains the `sg` source. The sources page gives resolution, update frequency and forecast span per model (12 of 20). Parameter tables mark required fields and defaults, and `datum` lists its seven values, but no types or ranges are given (7 of 15). Examples in Python, curl and JavaScript with sample responses, and a table of seven error codes. The sample JSON has trailing commas, and the descriptions of the three secondary swell fields are swapped (10 of 15). The path is versioned as /v2 and 410 marks legacy resources. No changelog was found, only blog posts about new sources (6 of 15).\n\n### Transparency \u0026 trust: Stormglass API +14\n\n- Meteosource Weather MCP (32): 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.\n- Stormglass API (46): Closed service with one short terms page, dated 17 March 2026. The FAQ limits commercial use to Medium and higher. The terms set no rules on storing, caching or redistributing data and do not say what licence the customer receives (10 of 30). The privacy text is a few paragraphs inside the terms. It says data is kept as long as necessary and account data until deletion, with no period for request data, and no DPA was found (8 of 30). No deprecation policy was found. The terms let the company modify or terminate any service at any time and change content without notice, and the docs list 410 for retired resources (1 of 20). HubSpot is the only third party named, and no hosting location is given (3 of 20).\n\n### Agent ergonomics: Meteosource Weather MCP +10\n\n- Meteosource Weather MCP (75): 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.\n- Stormglass API (65): This is an API with no MCP server. `params` chooses the fields returned, `source` the models, and `start` and `end` the hours. The default on `/weather/point` is every source, so each field comes back once per model unless `source` is set (20 of 25). Time ranges, a bounding box for tide stations and a 10-day cap per historical call. Nothing is paginated (14 of 20). Seven status codes are documented, and the 403 body we saw was `{\"errors\":{\"key\":\"API key is invalid\"}}`. 402 for a spent quota is unusual, the FAQ names a different code, and no body is documented for any error (11 of 20). All ten endpoints are read-only GETs, safe to retry (15 of 20). `lat`, `lng` and `params` are the only required inputs and times default to today in UTC. No official SDK was found (5 of 15).\n\n### Payments \u0026 pricing: Meteosource Weather MCP +5\n\n- Meteosource Weather MCP (30): 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.\n- Stormglass API (25): No x402, MPP or L402. The API's 402 means a spent quota (0). Plan prices are public without a login, in euros, with daily quotas and no per-call or overage price, 19, 49 and 129 euros a month (10 of 20). A free plan at 10 requests a day. The site says signup is always free. The signup form is drawn by script and we did not read it, so whether a card is asked for is not established, and the terms call the plan an evaluation not meant for indefinite use (15 of 20). A person signs up in a browser to get a key (0).\n\n## Score by category\n\n| Category | Weight | Meteosource Weather MCP | Stormglass API | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 35 | 34 | Meteosource Weather MCP +1 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 72 | 40 | Meteosource Weather MCP +32 |\n| Agent ergonomics | 13% (16.2 this run) | 75 | 65 | Meteosource Weather MCP +10 |\n| Security \u0026 auth | 14% (17.5 this run) | 42 | 44 | Stormglass API +2 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 30 | 25 | Meteosource Weather MCP +5 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 70 | 15 | Meteosource Weather MCP +55 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 32 | 46 | Stormglass API +14 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **50.9 · D** | **40 · E** | |\n\n## Facts side by side\n\n| Fact | Meteosource Weather MCP | Stormglass API |\n| --- | --- | --- |\n| Kind | MCP server | HTTP API |\n| Vendor | Meteosource | Storm Glass AB |\n| Hosted endpoint | `https://mcp.meteosource.com/mcp` | `https://api.stormglass.io/v2` |\n| Transports | Streamable HTTP | HTTP |\n| Auth | API key | API key |\n| Pricing | Freemium | Freemium |\n| x402 | no | no |\n| Licence | Proprietary service.

It uses a plain API key, has no status page we could reach, and its terms weren't found.\n\n**Stormglass API.** A read-only weather and marine API with about 70 hourly parameters, per-source values from named national models, tide data and ERA5 history from 2014. No OpenAPI file, status page, SDK or security page was found, the free plan allows 10 requests a day, and the docs and FAQ disagree on the status code for a spent quota.\n\n## Before you call either\n\n### Meteosource Weather MCP\n\n1. Call search_places first to resolve a location\n2. Split history requests over 400 location-days into shorter ranges\n3. Production tools need the Renewables plan; check which tools the key exposes\n4. Send the key in a header, never in a URL\n\n### Stormglass API\n\n1. Send the key as `Authorization: KEY` with no Bearer prefix. A missing or wrong key returns 403 with `{\"errors\":{\"key\":\"API key is invalid\"}}`\n2. Always pass `source=sg` or a short source list on `/weather/point`. The default is every source, which multiplies the size of each hourly record\n3. Treat 402 as a spent daily quota, not a billing failure, and stop until the next day. Read `meta.requestCount` against `meta.dailyQuota` on each response\n4. Use `/historical/point` for past dates, at most 10 days a call and nothing newer than about 7 days. `/weather/point` looks back 14 days only\n5. Send and read all times in UTC. Tide sea levels are relative to the chosen datum (MSL by default) and are not water depth\n\n## Questions\n\n### Which is better for AI agents, Meteosource Weather MCP or Stormglass API?\n\nMeteosource Weather MCP scores 50.9 (D) on agent readiness against Stormglass API's 40 (E), and leads in 5 of 7 scored categories.
