Can I use Matrix as a CLI?

Yes. KosmoKrator exposes a Matrix CLI through kosmo integrations:call and the provider shortcut command. Commands can return JSON for scripts, CI, and coding agents.

Can I expose Matrix through MCP?

Yes. The KosmoKrator MCP gateway can expose selected Matrix tools to clients such as Claude Code, Cursor, Codex, and other MCP-compatible tools.

Where are Matrix credentials stored?

Matrix credentials are configured in KosmoKrator's local integration settings and reused by CLI, Lua, and MCP gateway surfaces.

Can I deny write access for Matrix MCP tools?

Yes. Start the gateway with --write=deny for read-only clients, or use ask/allow only for trusted workspaces.

Matrix CLI for CI

Run integration calls from CI jobs with JSON output, explicit credentials, and predictable exit status.

Use this shape when a pipeline needs to read or update an external service. The Matrix CLI uses the same integration registry as the TUI, Lua runtime, and MCP gateway, but returns predictable command output for automation.

Command Shape

# Matrix CLI for CI
kosmokrator integrations:configure matrix --set access_token="$MATRIX_ACCESS_TOKEN" --enable --read allow --write ask --json
kosmo integrations:call matrix.matrix_list_rooms '{"limit":1,"from":"example_from"}' --json

Discovery Before Execution

Agents and scripts can inspect Matrix docs and schemas before choosing a function.

kosmo integrations:docs matrix --json
kosmo integrations:docs matrix.matrix_list_rooms --json
kosmo integrations:schema matrix.matrix_list_rooms --json
kosmo integrations:search "Matrix" --json
kosmo integrations:list --json

`matrix.matrix_send_message`	Write	room_id, body, msgtype, txn_id	Send a text message to a Matrix room. Uses a unique transaction ID to prevent duplicate messages.
`matrix.matrix_list_members`	Read	room_id, limit	List members of a Matrix room. Returns user IDs, display names, and avatar URLs.
`matrix.matrix_get_profile`	Read	user_id	Get a Matrix user's profile information, including display name and avatar URL.
`matrix.matrix_get_current_user`	Read	none	Get the currently authenticated Matrix user's information, including user ID and device ID.

Automation Notes

Use --json for machine-readable output.
Keep credentials out of argv by using environment variables or stored KosmoKrator configuration.
Configure read/write policy before unattended runs; use --force only for trusted automation.
Use the MCP gateway instead when the agent needs dynamic tool discovery inside a conversation.
