MCP Specification

MCP is a thin adapter over the same application use cases and authorization as REST. It owns no database or retrieval logic.

Read-only tools V1

• rag_search(query, spaces?, profile?, filters?)
• rag_get_context(query, spaces?, profile?, budget?)
• rag_answer(query, spaces?, profile?)
• rag_list_spaces()
• rag_get_document(document_id, version_id?)
• rag_get_citation(citation_id)

Resources

rag://spaces/{space}, rag://documents/{id}/versions/{version}, rag://citations/{id}.

Security

Remote HTTP transport uses scoped authorization. Tool schemas expose no raw filters or admin operations. Same effective-space calculation, rate limits, audit and data policies apply. Standard MCP surface is read-only; reindex/delete/grant management remains admin API/UI.
