Add a portable root plugin.json conforming to agent-plugins.org and make
mcp.json spec-conformant ($schema, explicit stdio type). Remove the
${ELEVENLABS_API_KEY} env interpolation from the portable mcp.json — the
spec only expands ${PLUGIN_ROOT}/${PLUGIN_DATA}, so spec-strict clients
would set the key to the literal placeholder string instead of inheriting
it from the environment. Cursor keeps its dashboard-variable interpolation
via a dedicated .cursor-plugin/mcp.json.
Both root files validate against the official 1.0.0 JSON Schemas, and the
Claude Code marketplace add/install flow was re-verified end to end.

Resolved conflicts with main (#2 switched to the hosted MCP server). Resolution: main's hosted-only direction wins everywhere; the Agent Plugins v1.0.0 conformance is reapplied on top of it.

What changed
Agent Plugins v1.0.0 just launched — an open, vendor-neutral plugin packaging standard backed by a steering committee including Cursor, OpenAI, Amazon, Microsoft, and Vercel. This PR makes the repo conformant while keeping the existing Cursor / Claude Code / Codex vendor manifests working unchanged.
plugin.json— the portable manifest required by the spec ($schema+name+ allowed metadata). The spec's schema is closed, so it deliberately omits vendor-only fields likedisplayName,logo, and component pointers (skills and MCP are auto-discovered fromskills/andmcp.json).mcp.jsonmade spec-conformant — added$schemaandtype: "stdio", and removed the${ELEVENLABS_API_KEY}env interpolation. This is the important fix: the spec only expands${PLUGIN_ROOT}/${PLUGIN_DATA}and leaves other placeholders literal, so a spec-strict client would have set the API key to the literal string"${ELEVENLABS_API_KEY}", clobbering the real key inherited from the user's shell. Without theenvblock, the stdio subprocess inheritsELEVENLABS_API_KEYfrom the environment — matching what the README already instructs..cursor-plugin/mcp.json— Cursor-specific MCP config that keeps the${ELEVENLABS_API_KEY}interpolation, since Cursor resolves it from the dashboardvariablesdeclared in its manifest..cursor-plugin/plugin.jsonnow points at it.Why
One repo now serves four surfaces: Cursor, Claude Code, Codex, and any future client implementing the open standard — with no repackaging.
