Today is the operative word: we check spintax.net MCP server 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.

analyze

analyze_spintax

Reports what the template needs and contains: refs (variables referenced), sets (#set macros, re-picked per reference), defs (#def, rolled once per render), includes, diagnostics, and best-effort construct counts. Answers "what variables must I supply" — it is NOT a variant-cardinality counter.

render

render_spintax

Renders up to 20 variants. With a seed the output is deterministic (variant i uses seed "<seed>#<i>"); without one it is random. The engine is lenient: structural mistakes never throw, they surface in the output — run validate_spintax first.

spintax

spintax_authoring_guide

Read this BEFORE writing or editing a spintax template — it is the canonical authoring guide the whole spintax toolchain is written against, not a tutorial. Pass the locale you will author in: for ru/uk/be and sr/hr/bs it carries the agreement and case rules that decide whether the variants read as human writing, which is the hard part and the part a valid template can still get wrong; for ar, the six plural forms and their order. Returns text to read, not a template.

validate

validate_spintax

Static validation: returns diagnostics with severity, stable code, message and 1-based line/column. No "error"-severity diagnostic means the template is structurally sound — read the warnings before rendering, because some of them (plural.locale-missing) mean a block will not resolve. Pass knownVariables for names you will supply at render time to silence their variable.undefined warnings.

spintax.net MCP server — questions

Answers built from our own checks of this server.

What can spintax.net MCP server do?

It exposes 4 tools, read directly from the server on our last check. Among them: analyze_spintax, render_spintax, spintax_authoring_guide, validate_spintax. 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 spintax.net MCP server working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 141 ms. The bar chart above shows every period we have measured.

How do I connect spintax.net MCP server?

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 spintax.net MCP server need an API key?

No. spintax.net MCP server 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 spintax.net MCP server?

It answers our handshake in 141 ms on average, which is faster than 86% 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.

How many people use spintax.net MCP server?

The npm package @spintax/mcp was installed 144 times in the last week. Week over week that is +37%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
