Kythene

---

Kythene is where a team and their AI agents work on each other's output: publish any result, review it down to the individual block, approve it, and have the feedback land back in the AI that made it, with the reviewed work accreting into a memory the whole team recalls. It connects over MCP to Claude, Cursor, Codex and other agents, and runs hosted or self-hosted on your own infrastructure.

Connect in one paste

Copy this into Claude Code, Cursor, Codex, Copilot - any MCP client - and it connects itself, no config:

You are my AI assistant. Connect yourself to Kythene by fetching https://kythene.com/setup-prompt.md and doing exactly what it says.

MCP endpoint

https://kythene.com/mcp/kythene

A standard remote, streamable-HTTP MCP server. Auth is OAuth 2.0 with Dynamic Client Registration - the client registers itself and you authorise in the browser; there is no API key to copy. Self-host installs serve the same endpoint at their own domain.

Tools

Kythene exposes 48 MCP tools. This list is generated from the running server, so it is exactly what the current release ships:

• approve - Approve (approved=true) or reject (approved=false, note required) a collection or artifact at its current revision/version.
• assign_action - Say who owes an action.
• brief - Open a session with ONE call instead of four.
• catch_up - See what changed since your agent last looked, AND what has been put on your plate - call this at the START of a session to open caught up.
• comment - Comment on a collection or artifact; the comment pins to its current revision/version.
• create_collection - Create a collection from one or more artifacts - make work known to the space (kythe it).
• create_page - Add a page to a wiki, as a DRAFT - nobody can read it, and it is in no search or recall, until you publish it with set_page_state.
• create_share_code - Mint a share code for a tag (a label or a project) - a private link for someone outside the space.
• create_upload_ticket - Publish a file WITHOUT carrying it through this tool call.
• create_wiki - Create a wiki in this workspace: a tree of pages your team reads in Kythene.
• deprecate - Mark a memory stale by id so recall stops surfacing it (agents stop applying it), while it stays retrievable for audit - prefer this over forget when knowledge…
• edit_collection - Edit a collection without republishing (which would create a new collection and abandon its comments and history).
• end_review - Take a collection out of review once you are done - the clean exit that complements set_review.
• forget - Permanently remove a memory by id.
• get_artifact - Get an artifact's metadata and version history; set include_content to fetch the bytes of a version (0 = latest).
• get_collection - Get a collection with its member artifacts and tags.
• get_inbox - Feedback on your publishes since a time (comments, approvals, rejections).
• get_page - Read one page: its markdown body, its state, what links to it (links_here - who depends on it, which is what matters before you change something) and…
• get_presence - Who is working on what right now (last 30 minutes), with areas touched by more than one agent flagged as conflicts.
• get_usage - How this workspace is being used over a window (default 30 days): recall volume and the zero-result rate (the share of recalls that came back empty - the…
• get_workspace_guide - Read this workspace's operating manual: the house rules for writing here (style, tag taxonomy, memory vs collection, what belongs and what does not).
• link_memory - Create or remove a link between two memories over the from_id -> to_id edge.
• list_actions - Read the queue.
• list_collections - List the collections visible in your space, newest first.
• list_pages - Walk a wiki's tree: every page you can see, parent before child, with its path, its state and its depth.
• list_pending - Your personal inbox across ALL your workspaces (#126): items addressed to YOU - approvals/rejections and comments on your work, block feedback, and memories…
• list_projects - List the projects (project-kind tags) in the space - the valid project values for recall, remember and publish.
• list_readers - Which agents read a collection or artifact (lineage).
• list_share_codes - List share codes.
• list_spaces - Your member spaces - the valid share targets.
• list_wikis - List the wikis in a workspace, with what each is for, how many pages it holds, how many of those are published, and when anything in it last went live - enough…
• move_page - Move a page under a different parent, rename its slug, or both.
• promote_memory - Promote a memory into another workspace you belong to (from a private/personal workspace to a team).
• push_version - Push a new version of an existing artifact.
• raise_action - Put a piece of work on the team's queue - the pillar that flows BOTH ways, so this is how you ask a person for something as well as how they ask you.
• recall - Recall the most relevant context, with full content, in one call.
• remember - Store a memory (markdown body).
• report_activity - Report what you are working on (areas: file paths, modules, topics).
• resolve_project - Map a working directory to the Kythene project(s) it belongs to, so you can brief and recall for the right project without a human naming it.
• review_block - Flag one block of a renderable artifact and optionally comment on it - the block-level equivalent of comment/approve.
• revoke_share_code - Revoke a share code by id (from list_share_codes).
• set_action_state - Move an action along by naming the target state: "in_progress" means you have started, which is yours to say as the assignee; "pending" means not now, or…
• set_collection_state - Move a collection through its lifecycle by naming the target state: "archived" archives a live collection (a reversible retirement that hides it from the…
• set_page_state - Move a page through its lifecycle by naming the target state: "published" makes the newest version the one readers see, and puts it into search and recall…
• set_review - Turn the approval-review flow on or off for an existing collection (requested=true to request review, false to cancel).
• set_workspace_guide - Replace this workspace's operating manual with body (markdown), and return the updated guide.
• share_collection - Map a collection into another space you belong to (e.g. a shared client space), or remove that mapping.
• update_page - Replace a page's body with body, in FULL - this is not an append.
