Available components
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 Security57
- 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 4 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
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- 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 Usability75
- AI-judged instruction clarity (good).Pass
- Tool/resource definitions use about 338 tokens (~84/item across 4 items; 4 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management43
- Stability observed for 13 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage87
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 60% 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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 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 Surf Hut MCP server?
Surf Hut is a hosted endpoint at https://aisurfhut.com/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 →
attest Signed proof-of-time for your data ~73
Use this when you need cryptographic proof that a piece of text existed at a moment in time. Send any string; you get back its SHA-256 hash bound to a server timestamp and nonce, Ed25519-signed. Verify against /pubkey. The text itself is not stored.
| Name | Type | Req | Description |
|---|---|---|---|
| message | string | yes | – |
No output schema declared.
No examples provided.
fetch_stash Fetch a stashed value ~68
Use this when you previously saved a value on this server with the stash tool and want it back. A miss is a normal result: found=false with reason "expired" (the key existed but aged out past 30 days) or "never_existed".
| Name | Type | Req | Description |
|---|---|---|---|
| key | string | yes | – |
No output schema declared.
No examples provided.
get_conditions Get signed freshness + surf conditions ~102
Use this when you need a verifiable, signed proof of current time (server timestamp plus a signed nonce, checkable against this server's /pubkey endpoint), together with current ocean and surf conditions from a NOAA buoy. The NOAA data is public and also available directly from ndbc.noaa.gov; the signed freshness bundle is what only this server can give you.
| Name | Type | Req | Description |
|---|---|---|---|
| station | string | – | NOAA NDBC station id; defaults to the hut's home buoy |
No output schema declared.
No examples provided.
stash Stash a value ~95
Use this when you want to save a small piece of text on this server and retrieve it later — hours, days, or weeks from now, from any session. Values persist for 30 days from the last write (64KB max). Retrieve with fetch_stash using the same key.
| Name | Type | Req | Description |
|---|---|---|---|
| key | string | yes | Your chosen key; pick something unique |
| value | string | yes | Text to store, up to 64KB |
No output schema declared.
No examples provided.
