Category Maps and Location
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 Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- 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 Usability70
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1528 tokens (~138/item across 11 items; 11 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 Management60
- Stability observed for 18 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage96
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 89% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 11 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
- Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

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 →

How do I install the Cosmic's Coast Map MCP server?
Cosmic's Coast Map is a hosted endpoint at https://coast.cosmicotter.ca/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.

What is the Cosmic's Coast Map MCP server?
Cosmic's Coast Map is an MCP server listed in the public MCP registry as io.github.brendoncampbell/coast-map. Tides, currents, marine forecasts and warnings for paddlers, anglers and small boats, 26 countries. This page covers its hosted endpoint (https://coast.cosmicotter.ca/mcp).
Is the Cosmic's Coast Map MCP server safe to use?
Cosmic's Coast Map scores 79 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 Cosmic's Coast Map MCP server expose?
Cosmic's Coast Map exposes 11 tools: find_stations, plan_paddle, tide_times, currents, best_low_tides, and 6 more. Their descriptions and schemas cost roughly 1,214 tokens of context every time the server is loaded.
Does the Cosmic's Coast Map MCP server require authentication?
No. We connected to Cosmic's Coast Map without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Cosmic's Coast Map MCP server still maintained?
Cosmic's Coast Map is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
