API Reference

This document describes the REST API exposed by the Molecule AI workspace server (Go/Gin, default port :8080). Clients include the Canvas frontend, workspace agents communicating over A2A, and external tooling such as the MCP server and CLI.

Base URL: http://localhost:8080 (development default) Rate limit: 600 req/min (configurable via RATE_LIMIT) CORS origins: http://localhost:3000,http://localhost:3001 by default (configurable via CORS_ORIGINS)

Authentication

Three middleware classes gate server-side routes:

• AdminAuth — strict bearer-only. Required for any route that can leak prompts/memory, create/mutate workspaces, or expose ops intel. Lazy-bootstrap fail-open when no live tokens exist globally.
• WorkspaceAuth — binds a bearer token to a specific workspace :id. A token for workspace A cannot be used against workspace B's sub-routes.
• CanvasOrBearer — accepts a bearer token OR a request Origin matching CORS_ORIGINS. Used only for cosmetic routes with zero data/security impact (currently PUT /canvas/viewport only). Do not extend to routes that leak data or create resources.

Full contract: docs/runbooks/admin-auth.md.

Routes

Method	Path	Handler
GET	/health	inline
GET	/metrics	metrics.Handler() — Prometheus text format; no auth, scrape-safe
POST/GET/PATCH/DELETE	/workspaces[/:id]	workspace.go — GET /workspaces, POST /workspaces, and DELETE /workspaces/:id require AdminAuth. PATCH /workspaces/:id enforces field-level authz: cosmetic fields (name, role, x, y, canvas) pass through; sensitive fields (tier, parent_id, runtime, workspace_dir) require a valid bearer token when any live token exists.
GET/PATCH	/workspaces/:id/config	workspace.go
GET/POST	/workspaces/:id/memory	workspace.go
DELETE	/workspaces/:id/memory/:key	workspace.go
POST/PATCH/DELETE	/workspaces/:id/agent	agent.go
POST	/workspaces/:id/agent/move	agent.go
GET/POST/PUT	/workspaces/:id/secrets	secrets.go (POST/PUT auto-restarts workspace)

GET	/workspaces/:id/model	secrets.go
GET	/settings/secrets	secrets.go — list global secrets (keys only, values masked)
PUT/POST	/settings/secrets	secrets.go — set a global secret {key, value}; auto-restarts every non-paused/non-removed/non-external workspace that does not shadow the key with a workspace-level override
DELETE	/settings/secrets/:key	secrets.go — delete a global secret; same auto-restart fan-out as PUT/POST
POST	/admin/workspaces/:id/tokens	admin_workspace_tokens.go — mint a real workspace bearer token; requires AdminAuth; plaintext is returned once
GET/POST/DELETE	/admin/secrets[/:key]	secrets.go — legacy aliases for /settings/secrets
WS	/workspaces/:id/terminal	terminal.go
POST/GET	/workspaces/:id/approvals	approvals.go

POST	/workspaces/:id/channels/:channelId/test	channels.go (test connection)
GET	/channels/adapters	channels.go (list available platforms)
POST	/channels/discover	channels.go (auto-detect chats for a bot token)
POST	/webhooks/:type	channels.go (incoming social webhook)
GET/PUT/DELETE	/workspaces/:id/files[/*path]	templates.go
GET	/canvas/viewport	viewport.go — open, no auth required (cosmetic, bootstrap-friendly)
PUT	/canvas/viewport	viewport.go — CanvasOrBearer middleware; accepts bearer OR Origin matching CORS_ORIGINS. Cosmetic-only route — worst case viewport corruption, recovered by page refresh.
GET	/templates	templates.go
POST	/templates/import	templates.go — AdminAuth required
POST	/registry/register	registry.go
POST	/registry/heartbeat	registry.go — requires Authorization: Bearer <token> once a workspace has any live token on file (legacy workspaces grandfathered)

POST	/bundles/import	bundle.go — AdminAuth required
GET	/org/templates	org.go (list available org templates)
POST	/org/import	org.go — AdminAuth required; applies resolveInsideRoot path sanitiser on template paths
GET	/events	events.go — AdminAuth required
GET	/events/:workspaceId	events.go — AdminAuth required
GET	/admin/liveness	inline — AdminAuth required. Returns per-subsystem supervised.Snapshot() ages; use to check health of scheduler/heartbeat goroutines

Database

Migration files live in workspace-server/migrations/ (latest: 022_workspace_schedules_source). Each migration ships as a .up.sql/.down.sql pair. The migration runner globs *.sql, filters out .down.sql files, sorts alphabetically, and executes each file on boot. All .up.sql files must be idempotent (CREATE TABLE IF NOT EXISTS, ALTER TABLE ... IF NOT EXISTS) because the runner re-applies every migration on every boot.

Key Tables

Table	Description
workspaces	Core entity — status, runtime, agent_card JSONB, heartbeat columns, current_task, workspace_dir
canvas_layouts	Per-workspace x/y canvas position
structure_events	Append-only event log (workspace lifecycle, agent, approval events)
activity_logs	A2A communications, task updates, agent logs, errors. error_detail is populated by the scheduler so cron run history can surface failure reasons.
workspace_schedules	Cron tasks — expression, timezone, prompt, run history, source ('template' for org/import-seeded, 'runtime' for Canvas/API-created), last_status (includes 'skipped' when the scheduler concurrency-skips a busy workspace)
workspace_channels	Social channel integrations (Telegram, Slack, etc.) with JSONB config and allowlist
agents	Agent records
workspace_secrets	Per-workspace encrypted secrets
global_secrets	Platform-wide encrypted secrets
workspace_auth_tokens	Bearer tokens; auto-revoked on workspace delete
agent_memories	HMA scoped memory (LOCAL / TEAM / GLOBAL)
approvals	Human-in-the-loop approval requests
