Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

File ships in the package but is absent from the source [пакет] index.mjs:1

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 19

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

audit

audit_endpoint

Readiness audit of any agent-facing URL: MCP handshake, CORS, discovery docs (llms.txt, mcp.json), and payment-offer behaviour. First call with url alone for the FREE grade and failing-check list. For the full findings and remediations, call get_offer with productType "audit" and productId "conformance-report", pay, then call audit_endpoint again with the same url plus paymentTx and paymentOffer. This tool both previews and redeems the paid report; no separate delivery tool is needed.

audit_theme

Run a read-only theme audit on a public HTTP(S) page, free in full. Fetches but never modifies the page, then checks inline style CSS for brace errors, token gaps, incomplete dark themes, missing body backgrounds, and WCAG body-text contrast. External stylesheets are counted but not fetched. Use audit_endpoint instead for MCP, CORS, discovery, and payment readiness.

request

check_request

Check a private ticket from request_fix. Returns pending, declined, not-eligible, redeemed, or the full fix free once an eligible new fix is stocked. This call may atomically consume the ticket's one-time delivery, so save the returned body. Use get_fix when you already have a catalog id; do not create another request while this ticket is pending.

request_fix

Ask for a fix this store does not have yet. If we already stock it (matched on either field) you get the id straight back and no ticket. Otherwise you get a ticket; when we stock THAT fix, check_request returns it to you FREE, once. A ticket only ever redeems a fix created after the request: fixes that already existed when you asked are not free, whatever the request said. No contact details are collected. Set publish: true ONLY if the text may appear on a public wanted board — never include secrets, tokens, internal hostnames, or file paths.

catalog

list_catalog

Browse every stocked error signature, title, tag, confidence label, and free-sample flag without ranking or creating an offer. Use search_fixes instead when diagnosing a specific error; it returns the best match and any purchase-ready checkout.

fix

get_fix

Get or redeem a fix after search_fixes or list_catalog identifies the id. Free samples return immediately. For a paid fix, call with the id alone to receive a free diagnosis preview, confidence and compatibility, dollar price, signed Base Pay USDC and exact-ETH offers, and one pay-and-redeem action; then call once more with the matching paymentTx and private paymentOffer. Never pay again merely because an existing proof is pending or denied.

fixes

search_fixes

Use this first for an exact error or distinctive symptom. Returns up to three confident ranked matches. A free top match includes the full fix. A paid top match includes a free diagnosis, confidence and compatibility, dollar price, signed USDC/Base Pay and exact-ETH rails, and one pay-and-redeem action; do not call get_offer. Use list_catalog to browse, get_fix only with a known id or payment proof, and request_fix only after an honest miss.

free

get_free_skill

Return the complete Markdown body of one free workflow listed by get_overview. No account, payment, paid body or private data. Use list_skills/get_skill for premium products instead. This tool supports clients that cannot read MCP resources.

merch

list_merch

Browse the KnownFix Merch Store. Returns fixed product ids, lines, formats, and privacy-safe tracked links to the human Fourthwall storefront. Fourthwall shows the current localized price, options, tax, shipping, and availability. This tool does not place an order or collect checkout data.

offer

get_offer

Create or refresh a one-hour signed bearer offer for a chosen skill, bundle, audit, or fix. Do not call this after a paid search_fixes result or an unpaid get_fix/get_skill result because those responses already include both payment rails. Choose USDC for Base Pay or ETH for exact wei; with no product arguments, this returns the general settlement document.

order

order_service

Create a private ticket and signed Base USDC/ETH checkout for an eligible automated service only. Do not call for requiresScopeApproval services (SaaS security, Microsite Launch) or paymentTiming:after-verified-delivery (Verified Repo Fix); these require manual scope approval via their published page. Accepts authorized public HTTPS targets only. Obtain operator spending approval. Never send credentials or confidential data. Keep the returned svc_ ticket private.

overview

get_overview

One free overview of all KnownFix offerings: complete free-workflow resource URIs, three browser-local tools and their companion guides, catalog routes, premium outlines and service prices/scopes/ordering boundaries. No account, payment, signed offer or order creation. Use search_fixes first for an exact error; list_services for full engagement terms.

report

report_checkout_blocker

Use only after a signed KnownFix checkout cannot proceed before a payment hash exists. Reports one closed-vocabulary blocker tied to the valid offer; at most one aggregate count is accepted per offer. No wallet address, token, transaction hash, query, or free-form text is published. Do not call after payment; redeem with get_fix, get_skill, or audit_endpoint instead.

service

check_service_order

Check a private service order by its svc_ ticket. With paymentTx and paymentOffer, atomically confirms exactly one matching Base payment and moves the order into review. Without payment fields, returns current status; once complete, it returns the private Markdown report and SHA-256 digest. Keep the ticket and signed offer private.

services

list_services

Compare all current KnownFix reviews, Verified Repo Fix and Microsite Launch. Returns complete scope, deliverables, prices, delivery targets and limitations. Services requiring scope approval or payment after verified delivery are manual: use their order page, not order_service. SaaS security requires explicit written testing authorization. Other services use private-ticket checkout only after operator spending approval and target authorization.

skill

get_skill

Get or redeem a premium skill or multi-fix bundle after choosing with list_skills. Call with the id alone to receive the free outline, dollar price, signed Base Pay USDC and exact-ETH offers, and one pay-and-redeem action. After payment, call once more with the matching paymentTx and private paymentOffer for the complete SKILL.md or assembled bundle decision tree, fix bodies, verification commands, update guidance, and sources. Do not use this for individual fixes; call get_fix instead. Never pay again merely because an existing proof is pending or denied.

skills

list_skills

Compare premium skills and multi-fix bundles. Returns current ids, free outlines, provenance, formats, and exact prices while full bodies remain paid. Call get_skill with a chosen id for signed USDC and ETH checkout; use search_fixes for a single error.

submission

check_submission

Check the private submissionId returned by submit_fix. Returns only pending-review, accepted, declined, or cataloged state and, when cataloged, the stocked fix id. It never returns submitted text or contributor details and creates no side effects. Use get_fix with catalogId when cataloged; do not resubmit merely because review is pending.

submit

submit_fix

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. Returns a private submissionId; save it and call check_submission for pending, accepted, declined, or cataloged status. Submitted text and contributor details are never returned by the status tool. Revenue-sharing for accepted contributions is planned, not yet live.

KnownFix — questions

Answers built from our own checks of this server.

What can KnownFix do?

It exposes 19 tools, read directly from the server on our last check. Among them: audit_endpoint, audit_theme, check_request, check_service_order, check_submission, get_fix and 13 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is KnownFix mostly used for?

Its tools cluster around audit and request. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is KnownFix working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 1495 ms. The bar chart above shows every period we have measured.

How do I connect KnownFix?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does KnownFix need an API key?

No. KnownFix completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 19 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is KnownFix?

It answers our handshake in 1495 ms on average, which is faster than 1% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use KnownFix?

The npm package knownfix was installed 184 times in the last week. Week over week that is -21%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is KnownFix open source?

The code is open source: it is published under the MIT licence, written in HTML, 1 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at knownfix-backend-28.b-hash88.deno.net, which runs on its operator's own terms.
