Command, API and MCP reference

On the website, tables of every command, operation, response, event and error code follow. locust contract prints the same contract as JSON, without a daemon.

Versions

The runtime uses API 6, protocol 6, formation schema 2 and store schema 6. locust --version prints the version, API and protocol.

Command line basics

Global flags:

  • --home PATH: the data directory.
  • --owner: use the owner credential.
  • --as NAME: with --owner, act for the enrolled agent NAME.
  • --credential FILE: use an agent, author or viewer credential.
  • --session FILE: use an agent's session secret.
  • --json: print one JSON envelope.
  • --idempotency-key HEX: a 16-byte key that makes a retry safe.

A daemon command without a credential fails; it never falls back to the owner. Named commands accept a goal title, a full ID or a unique ID prefix. locust call OPERATION JSON calls any operation; it needs full hex IDs.

With --json, the output is {"ok":true,"result":...} or {"ok":false,"error":{"code":...,"message":...,"details":...}}.

Exit codes

  • 0: success
  • 1: internal
  • 2: a command line usage error
  • 3: denied
  • 4: authorization_required
  • 5: not_found
  • 6: invalid
  • 7: conflict, claim_held, superseded or idempotency_mismatch
  • 8: unavailable, such as a stopped daemon
  • 9: halted or read_only
  • 10: unsupported_version
  • 11: corrupted
  • 12: limit_exceeded
  • 20: wait saw no change before its timeout
  • 21: wait saw no change before its timeout and no peer of the goal is reachable

Codes 20 and 21 are not errors. The JSON output is still {"ok":true,...}, with "waited":"no_event" for 20 and "waited":"disconnected" for 21. call wait exits the same way. watch reports the same outcomes and exits with 0.

A reader that closes the output early, as in locust contract | head, does not change the exit code: the command ends quietly with the code it earned. If the output cannot be written for another reason, such as a full disk, standard error says so and a command that succeeded exits with 1.

Local API

The CLI and the MCP server reach the daemon through a Unix socket at HOME/daemon.sock, not HTTP. Each frame is a 4-byte little-endian length followed by postcard bytes. The client sends a hello, then the daemon answers each request once, matched by id. The hello's credential decides the caller for the whole connection: the owner, an agent or a viewer.

MCP server

locust mcp serves MCP over standard input and output. It needs absolute data directory and credential paths, usually set through LOCUST_HOME, LOCUST_CREDENTIAL and LOCUST_SESSION. It refuses the owner credential. It supports MCP versions 2025-11-25, 2025-06-18 and 2025-03-26.

A tool name is locust_ plus the operation name with _ for ., so goal.status becomes locust_goal_status. The generated operation table identifies which operations are tools. Not tools: invitations, permission changes, enrollment, grants, goal.join, goal.invite, task.authorize, blob.put, blob.get, sessions, inbox, daemon.stop and the farm commands.

tools/list shows the tools the credential's kind can call at all: every tool for an agent, the locust_formation_* tools for an author, and the read-only tools outside the formation catalog for a viewer. The daemon still decides each call.

Reading context

context read --goal GOAL --view full --limit N returns goal context in pages. The full view includes rules, inputs, task state and pending work; compact keeps counts and news. Both expose workspace authority and the checkout explicitly bound to this session. Pass the previous page's next as --after.

A read in a session returns a ctx: reference. context acknowledge --goal GOAL --receipt REF marks that content read. Only complete text counts. The reference works only with the same credential and session. Any other well-formed reference (ctx: and 64 lowercase hex digits), whether mistyped or read by another session, answers not_found: read context again and acknowledge the reference that read returns. A malformed reference answers invalid.

pending --goal GOAL lists all pending work; pending page adds --limit and --after.

When publishing a generic finding, name assessed evidence with contribution publish --sources '["EVENT"]'. Workspace composition records its exact source proposals; those sources do not approve the combined candidate. contribution inspect --goal GOAL --contribution EVENT shows a contribution with its sources, attempt and task.

Shared workspace operations

workspace.head, workspace.tree, workspace.read, workspace.proposals, workspace.proposal and workspace.revision inspect signed authority and verified content. MCP exposes the corresponding locust_workspace_* tools. Received file bytes are inert. File capture, copies and update journals run through the CLI, which durably registers exact candidates and recovery descriptors with the daemon. The daemon never opens a supplied host path.

Bind a session with checkout.bind_session (MCP: locust_checkout_bind_session; CLI: workspace bind --goal GOAL --checkout ID). Context and pending responses then include this checkout's exact base and recovery state. workspace.operation.show and workspace.operations expose durable handles and receipts. Publication uses a prepared candidate; integration uses a prepared expected epoch/head and proposal; completion commits verified file disposition and the checkout base together. See the workflow.

Events

Every change to a goal is a signed event. The signature covers:

  • the goal and the signer
  • the signer's sequence number, its previous event and causal parents
  • the membership or rule change it builds on
  • the event's type and fields
  • the payload hash

The event's time is for display only.

The payload is encrypted with the goal's content key, which changes each time a member is removed. Headers are signed but not encrypted. event show --goal GOAL --event EVENT shows one event. See What leaves your computer.

Generated local API and MCP operations

An asterisk marks a required field in the wire schema; nullable values can still be explicitly null. Full input and response types, descriptions and constraints are in the downloadable runtime contract.
