docs(website): launch Rivet MCP

[NicholasKissel]

Post

• Adds src/content/posts/2026-09-10-introducing-rivet-mcp/page.mdx (changelog, published 2026-09-10).
• Canonical URL: https://rivet.dev/changelog/2026-09-10-introducing-rivet-mcp/
• Covers client setup (Claude Code, Codex, Cursor, Gemini CLI, VS Code), example prompts, inline Actor Inspector, the search/execute model, and scoped endpoints. Local mode is intentionally omitted (@rivet-dev/mcp is not published yet).

Artwork

• Hero image is not wired yet. Once https://assets.rivet.dev/website/blog/2026-09-10-introducing-rivet-mcp/image.png is uploaded to R2, add image: true to the frontmatter.

Notes

• The composed JavaScript example uses the API shapes verified against the live MCP server (filters wrapper on rivet.actors.list, method: "get" on the actor ref, action result under body.output). The existing examples/docs/mcp/one-request.js snippet predates that and should be updated separately.

Validation

• astro build passes (449 pages); post page renders all sections and the tabbed CodeGroup.
