MCP server v2.7.0: Organization discovery, Sanity development rules, and improved tool outputs

New Features

List organizations tool. New list_organizations tool to discover organization IDs before creating projects.

Sanity development rules. New list_sanity_rules and get_sanity_rules tools expose framework-specific and topic-specific Sanity development guides (Next.js, Astro, Nuxt, schemas, GROQ, visual editing, and more).

Improvements

Automatic CORS setup. create_project now automatically adds a CORS origin (http://localhost:3333 by default) enabling local development without manual configuration.

Clearer draft discard. Renamed version_discard_document to discard_draft for better discoverability when users ask to discard drafts without deleting the entire document.

Cleaner tool outputs. Restructured outputs from list_projects, list_releases, list_datasets, list_embeddings_indices, and query_documents for better LLM consumption and token efficiency.

Fixes

OAuth metadata URLs. Removed trailing slashes from OAuth discovery endpoints to fix compatibility with strict URL matching clients.
