Available tools 2

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

seed
get_seed_format
Returns the complete specification (markdown) for calaf_seed: 1 JSON documents — the format to follow when a user asks for a Calaf seed. Read it before authoring; then check your draft with validate_seed.
validate
validate_seed
Runs a draft seed document through the exact parser the Calaf app imports with. Pass the entire JSON document as a string. Returns per-section counts and the precise issue list (path, severity, message): severity "error" means nothing imports; "dropped" means that row or field is discarded and the rest lands. Fix the issues and validate again until clean before delivering the file to the user.

Calaf Seed Tools — questions

Answers built from our own checks of this server.

What can Calaf Seed Tools do?
It exposes 2 tools, read directly from the server on our last check. Among them: get_seed_format, validate_seed. 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 Calaf Seed Tools working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 29 of 91 checks got a reply (31.9%), average response time 241 ms. The bar chart above shows every period we have measured.
How do I connect Calaf Seed Tools?
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 Calaf Seed Tools need an API key?
No. Calaf Seed Tools completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Calaf Seed Tools?
It answers our handshake in 241 ms on average, which is faster than 57% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Calaf Seed Tools open source?
We cannot say either way: 0 stars on GitHub and 1 open issue, but we could not determine the licence, and without one the code is not open source by default.
