Integrations
Connect any MCP client to your project memory.
Knownbase is a remote MCP server: one endpoint, two authentication options, and nothing to install. Every client below reads and writes the same workspace.
The endpoint
https://knownbase.dev/mcp
Authenticate with OAuth (the client opens a browser and you pick a workspace) or with an Authorization: Bearer kb_... key from Settings → Workspace & MCP.
Set up your client
Claude Code
One command, OAuth sign-in, no key to paste. Setup guide →
Codex
One MCP server entry, plus the AGENTS.md section that makes it stick. Setup guide →
Cursor
One entry in .cursor/mcp.json, works in chat, Composer and agent mode. Setup guide →

Anything else that speaks MCP
Windsurf, Zed, local agents, your own client. Same URL, same tools. Tool reference →
What every client gets
search_notes— query by text, project, tag, status or last-modified date. Lean results by default so search stays cheap in tokens.get_note/get_notes— one note in full, or up to 50 by id in a single call.upsert_note— create or update, with partial updates so one field can be fixed without touching the rest.list_projects,list_note_revisions,get_note_revision,delete_note,rename_project,rename_tag,backup_project,workspace_info,usage_summary.
Full descriptions, argument shapes and rate limits are in the documentation.
One workspace, many agents
The reason to connect more than one client is that the memory belongs to the project rather than to the tool. A constraint discovered by Claude Code is retrievable by Codex, by Cursor, and by a teammate's agent, without anyone copying anything. How that works in practice →
