#MCP reference

This is the complete catalog behind the workflows in Orchestration and Common workflows. You normally ask for an outcome in natural language and let the agent choose the tools.

JCode can inject these tools into every new agent it launches. Open Settings → your host → Agents and turn on Enable JCode tools, or set daemon.mcp.injectIntoAgents to true.

Depending on the provider, JCode delivers the catalog through its native tool interface or MCP. The capabilities are the same either way.

The MCP server itself is controlled by daemon.mcp.enabled. Existing agents may need a reload.

#Mental model

Workspaces decide where work happens; agent parentage decides who owns the work.

• An agent that calls create_agent without a workspaceId gets a subagent in its own workspace.
• Passing a workspaceId places that subagent in another workspace without detaching it from its parent.
• A top-level MCP caller without a workspace gets a new local workspace.
• Create a workspace first when you need worktree isolation, a specific branch, or a pull request checkout.

MCP does not expose an agent-detach tool. Detaching is a manual user action in the app or CLI.

#Tools

#Agents

Tool	Function
create_agent	Create an agent, optionally placing it in an existing workspace with workspaceId.
send_agent_prompt	Send a task to a running agent.
get_agent_status	Return the latest snapshot for an agent.
list_agents	List recent agents as compact metadata.
cancel_agent	Abort an agent's current run but keep the agent alive.
archive_agent	Soft-delete an agent and remove it from the active list.
kill_agent	Terminate an agent session permanently.
update_agent	Update an agent name, labels, or runtime settings such as mode/model/thinking/features.
get_agent_activity	Return recent agent timeline entries as a curated summary.
set_agent_mode	Switch an agent's session mode.

#Workspaces

Tool	Function
create_workspace	Create a local or worktree-isolated workspace. Worktrees can branch off, check out a branch, or a PR.
list_workspaces	List active workspaces and their directories and isolation.
rename_workspace	Change the user-visible name of the current or specified workspace.
archive_workspace	Archive a workspace and the sessions it owns.

For worktree isolation, create_workspace accepts the same useful choices as the app: branch off from a base, check out an existing branch, or check out a pull request. The worktree remains an implementation detail of the workspace lifecycle.

#Terminals

Tool	Function
list_terminals	List terminal sessions for one working directory or all working directories.
create_terminal	Create a terminal session for a working directory.
kill_terminal	Kill a terminal session.
capture_terminal	Capture plain-text output from a terminal session.
send_terminal_keys	Send text or special key tokens to a terminal session.

#Schedules and heartbeats

Both use the same cron engine, but they have deliberately different interfaces.

Tool	Function
create_schedule	Create a cron schedule that starts a new agent for each run.
list_schedules	List new-agent schedules managed by the daemon.
inspect_schedule	Inspect a schedule and its run history.
pause_schedule	Pause an active schedule.
resume_schedule	Resume a paused schedule.
update_schedule	Change a schedule's cron, prompt, agent settings, limits, or other settings.
schedule_logs	Return recent runs and output for a schedule.
run_schedule_once	Start one new-agent schedule run without changing its cron.
delete_schedule	Delete a new-agent schedule permanently.
create_heartbeat	Send a recurring cron-backed prompt into the current agent.
delete_heartbeat	Delete one of the current agent's heartbeats.

MCP heartbeats are ephemeral: create or delete them. To change one, delete it and create a replacement. Pause, resume, update, inspect, logs, and run-once apply to new-agent schedules only.

#Providers

Tool	Function
list_providers	List configured agent providers, availability, and modes.
list_models	List models for an agent provider.
inspect_provider	Inspect compact provider capabilities and draft feature settings.

#Permissions

Tool	Function
list_pending_permissions	Return pending permission requests across agents.
respond_to_permission	Approve or deny a pending permission request.

#Browser

Browser automation is opt-in and adds tools for opening tabs, reading pages, clicking, typing, and taking screenshots. See the Browser tools reference.

#Voice

Tool	Function
speak	Speak text through daemon-managed voice output. Available only in voice-enabled sessions.
