## 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 2026-11-05.

- **Endpoint Security**: 80/100
  - 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 is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - 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**: 70/100
  - AI-judged instruction clarity (good).
  - 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.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 60/100
  - Stability observed for 18 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 96/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 89% 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 11 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 60/100
  - Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28.

- `lng` (number, required): Longitude in decimal degrees (WGS84), negative west of Greenwich.

### `coast_map_pass` (~75 tokens)

Coast Map Pass: what it adds and how to get it

What the Coast Map Pass adds over the free map (offline regions for trips with no signal; longer tide and current ranges for assistants), its prices (CA$5 a month or CA$55 a year), whether it is on sale yet, and the purchase or support links. Covers offline use, longer tide ranges and upgrading.

### `start_pass_purchase` (~71 tokens)

Start buying the Coast Map Pass in this conversation

Begin a Coast Map Pass purchase without leaving the conversation: returns checkout links (CA$5 a month or CA$55 a year, Stripe, no account) tagged with a purchase reference, or says the pass is not on sale yet. The user pays in their browser; the reference identifies that payment afterwards.

### `pass_status` (~80 tokens)

Collect the pass key after the user has paid

Checks whether the payment for a purchase reference has completed. Returns pending (with a retry interval) or paid with the pass key, which is sent as "Authorization: Bearer <key>" from then on, plus a link that activates the pass in the user's own map.

Input parameters:

- `reference` (string, required): The reference from start_pass_purchase (ag_…).

### `water_temperature` (~60 tokens)

Sea surface temperature

Water temperature from the nearest buoy within 40 km, otherwise satellite sea surface temperature.

## Common questions

### 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.
