MotionSpec — web animation accessibility is an MCP server with 5 tools an agent can call, among them motion_audit, motion_catalog, motion_compile. It answers at https://api.motionspec.dev/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 20 October 2026, succeeded.
Web animation accessibility MCP: GSAP, static CSS checks, prefers-reduced-motion, WCAG 2.2.2/2.3.3.

| Tool | What it does |
|---|---|
motion_audit | Requires a Dev Key ($39/mo) or Agency plan ($249/mo) on the hosted endpoint (motionspec.dev/pricing?src=mcp). Static motion-a11y checker: fetches a URL's HTML + linked stylesheets and scans the CSS for (1) animation/transition that moves wi Inputs: url |
motion_catalog | Returns the catalog of verified motion primitives (names, purpose, parameter schemas, defaults) plus the authoring rules for writing a MotionSpec. Call this FIRST, then write the spec yourself and validate it with motion_validate (motion_co |
motion_compile | Requires a Dev Key ($39/mo) or Agency plan ($249/mo) on the hosted endpoint (motionspec.dev/pricing?src=mcp); runs locally for free with 'npx -p motionspec motion compile <spec.json>' (MIT). Validates (fail-closed) and deterministically com Inputs: spec, specName |
motion_stats | Requires a Dev Key ($39/mo) or Agency plan ($249/mo) on the hosted endpoint (motionspec.dev/pricing?src=mcp). Summary of routing/compile telemetry (counts per outcome). Escalation clusters indicate which new primitive the catalog needs next |
motion_validate | Checks a MotionSpec against the schema, the primitive allow-list, parameter bounds and injection rules. Fail-closed: returns ok=false with precise errors. Returns {ok, errors, warnings, deprecations, catalogVersion}. IMPORTANT: warnings[] c Inputs: spec |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://api.motionspec.dev/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
