Kimun
Terminal Markdown notes app with search, a scriptable CLI and an MCP server.
Kimun is a local-first Rust notes app for plain Markdown vaults with a TUI, a CLI and a built-in MCP server over stdio. The MCP server has 18 tools for notes, properties, links and journals plus 7 review prompts. An optional server adds semantic search and question answering over your notes.
- you keep notes as Markdown files and want your agent to search, link and journal in them
- you live in a terminal and want an Obsidian-compatible vault with scriptable access
- README warns the app is in heavy development and config or themes may break after updates
- semantic search and Ask need the separate kimun-server and an embedding model download of a few hundred MB
- One person writes almost all the code; outside use is small but real
- The Docker image is the optional kimun-server, not the notes app

Adaptable: what is yours to change
Make it yours
Light edit4 things to edit
config.toml sets theme, key bindings, leader-key tree, sort order, workspaces and the optional server URL. These are personal interface settings, not business behavior. The MCP review prompts are compiled into the Rust source (tui/src/cli/commands/mcp/prompts.rs), so changing them needs a code edit.

Operable: what an agent can drive
Interface
OfficialMCP serverpublished by the builderlocal
How an agent can drive an Operable Listing, in five levels: native (built for the agent as the primary interface), official (the Builder ships an agent interface), wrapped (a third party wraps the software's API), config (an agent can only drive it by editing files), gui (screen control only). An interface is official only when it is published by the same organization that ships the software. GUI-level Listings are allowed and sorted last.
Reach
Partial coverage. 8 of 10 jobs reachable through the stated interface.
| Job | Through the interface | Evidence |
|---|---|---|
| Create, append to and edit notes | Reachable | MCP tools create_note, append_note, overwrite_note, replace_in_note |
| Delete notes | Reachable | MCP tool delete_note (marked destructive, backed up first) |
| Search notes | Reachable | MCP tool search_notes; CLI kimun search |
| Read notes and list the vault | Reachable | MCP tools show_note, list_notes, get_chunks; notes also exposed as note:// resources |
| Follow links and backlinks | Reachable | MCP tools get_backlinks and get_outlinks |
| Read and set frontmatter properties | Reachable | MCP tools get_properties, set_property, remove_property |
| Rename and move notes with link updates | Reachable | MCP tools rename_note and move_note |
| Journal and quick capture to the inbox | Reachable | MCP tools journal and quick_note; CLI kimun journal append |
| Manage workspaces (vaults) | Not reachable | No MCP tool in tui/src/cli/commands/mcp/mod.rs; the CLI covers it with kimun workspace init/list/use/rename/remove/reindex |
| Semantic search and Ask over notes | Not reachable | No MCP tool or CLI command. The optional kimun-server exposes POST /api/answer and GET /api/job/{job_id} over HTTP with a bearer token |
