Trust breakdown (6 categories)

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 →

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 8 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 Usability77

AI-judged instruction clarity (good).Pass
Tool/resource definitions use about 786 tokens (~98/item across 8 items; 8 tools + 0 resources), lean.Pass
Usage-examples check failed: none of the tools include examples. See how to fix → Fail

Stability & Change Management20

Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

Tool Coverage92

100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
75% of tool parameters carry a description.Partial

Capabilities100

Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

MCP tools · 8 exposed · ~670 tokens

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.

Tool Tokens

audit_endpoint ~83

Free readiness audit of any agent-facing URL: MCP handshake, CORS, discovery docs (llms.txt, mcp.json), and payment-offer behavior. Returns a graded, machine-readable report with remediations. This is the check KnownFix ran on itself.

Input Output Examples

Name	Type	Req	Description
url	string	yes	Base URL to audit, e.g. https://your-agent.example.com

No output schema declared.

No examples provided.

get_fix ~99

Get a fix body. Free-sample entries return immediately. Paid entries need paymentTx: the hash of a mined payment of perFixWei to the treasury on Base mainnet chain 8453 (see get_offer). One payment redeems one fix.

Input Output Examples

Name	Type	Req	Description
id	string	yes	Fix id from search_fixes or list_catalog
paymentTx	string	–	0x-prefixed tx hash of your on-chain payment (omit for samples)

No output schema declared.

No examples provided.

get_offer ~26

The machine-readable offer: price, treasury address, chain, and the exact redemption route.

Input Output Examples

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

get_skill ~84

Buy a skill: pay its exact unique priceWei (see list_skills) to the treasury on chain 8453, then call with paymentTx. Returns the full SKILL.md. One payment, one skill delivery.

Input Output Examples

Name	Type	Req	Description
id	string	yes	Skill id from list_skills
paymentTx	string	–	0x tx hash of your on-chain payment

No output schema declared.

No examples provided.

list_catalog ~30

The full free tier: every error signature, title, tags, confidence, and which entries are free samples.

Input Output Examples

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

list_skills ~130

Purchasable agent skills (free outline + provenance; body paid; each unique non-round price is the payment's join key). In stock: evm-payment-verification @ 0.00021037 ETH on Base (~$0.80); webflow-image-pipeline @ 0.00018743 ETH on Base (~$0.71); webflow-mcp-helper @ 0.00082951 ETH on Base (~$3.15); webflow-bundle @ 0.000915317 ETH on Base (~$3.48, vs 0.00101694 solo).

Input Output Examples

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

search_fixes ~82

Search KnownFix for your error (free). Paste the error text verbatim; returns ranked candidates with confidence labels — and when the top match is one of the 10 free samples, its FULL fix body is included in the response, no payment. An empty result is an honest miss.

Input Output Examples

Name	Type	Req	Description
query	string	yes	The error message or symptom, verbatim

No output schema declared.

No examples provided.

submit_fix ~136

Offer a fix for the catalog. Submissions are reviewed by the operator before listing; include a reproduction so the fix can be verified rather than trusted. Revenue-sharing for accepted contributions is planned, not yet live — that is stated here so you can decide with open eyes.

Input Output Examples

Name	Type	Req	Description
cause	string	–	–
contributor	string	–	How to credit/reach you: name, URL, or wallet address
fix	string	yes	–
reproduction	string	–	How to reproduce the error and verify the fix
signature	string	yes	The exact error string a stuck agent would search
title	string	yes	–

No output schema declared.

No examples provided.
