Nothing serious here today

Today is the operative word: we check Mend every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 4

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

mend
mend_check_json
Use when you need to know whether text is strictly valid JSON, and if not, exactly where it breaks. Strict RFC 8259 check (the same accept/reject as JSON.parse). Returns line, column, the offending line with a caret and whether Mend can repair it. Use mend_repair_json to fix it. Up to 100,000 characters.
mend_outline_json
Use when you are about to read a big JSON response, log or export into context, before loading it: returns a compact outline of the structure (keys, types, array lengths, one example per repeated shape) so you can plan a query without spending tokens on the whole document. Repairs the JSON first if needed. Follow with mend_query_json to pull only the values you need. Up to 100,000 characters.
mend_query_json
Use when you need specific fields from a JSON document without reading all of it: $.users[0].name, $.items[*].id, $.a.b[-1], $.list[1:3], $..email (recursive). Returns each match with its exact path, type and value. Repairs the JSON first if needed, so broken input still works. Up to 100,000 characters.
mend_repair_json
Use when JSON from an LLM, API, log, config or copy-paste fails to parse (JSON.parse error, "Unexpected token", "Expecting property name"), or the user pastes JSON with trailing commas, single quotes, unquoted keys, comments, Python True/False/None, NaN, missing commas or brackets, a ```json fence, text around it, or output that was cut off. Deterministic repair: returns valid, formatted JSON plus a list of every fix with line and column. Values are never rewritten, so big numbers, number formatting and key order stay exactly as written (re-asking a model to "fix the JSON" changes data and costs tokens). If the text is already valid it says so. Up to 100,000 characters.

Mend — questions

Answers built from our own checks of this server.

What can Mend do?
It exposes 4 tools, read directly from the server on our last check. Among them: mend_check_json, mend_outline_json, mend_query_json, mend_repair_json. 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 →
Is Mend working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 17 of 17 checks got a reply (100.0%), average response time 88 ms. The bar chart above shows every period we have measured.
How do I connect Mend?
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 Mend need an API key?
No. Mend completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Mend?
It answers our handshake in 88 ms on average, which is faster than 93% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
