Feature Request: Surgical/Partial Document Editing via API

We're building an agent-first knowledge base on Outline Cloud where AI agents (via MCP) do ~80% of the content curation. Love the product and the built-in MCP server - it's exactly what we needed. The one major friction point: the documents.update endpoint only supports replace, append, and prepend. To change a single paragraph mid-document, we have to send the entire document body back. For a 300-line doc where we're fixing one sentence, that's a lot of tokens and unnecessary data transfer. Proposed solutions (any of these would work) • A search-and-replace editMode - e.g., oldText/newText pairs, similar to how code editors handle find-and-replace • A patch-style endpoint - accepts line ranges or content diffs • Block or section-level addressing - edit by heading or stable block ID Why this matters AI agents (Claude, GPT, etc.) connecting via the MCP server frequently need to make small, targeted edits to existing documents - fix…
