Hongming Wang af931aa8da refactor(mcp-server): DRY envelopes, typed apiCall, explicit re-exports Second-pass cleanup after the monolith split. Addresses every issue from the code-review pass. Core additions in src/api.ts: - toMcpResult(data) + toMcpText(text): single source of truth for the MCP text-content envelope (was ~87 duplicated literals) - ApiError type + isApiError(v) guard: typed discriminated-union for the error-by-value pattern; replaces open-coded shape checks - apiCall<T = unknown>: generic so callers can document expected response shape without unchecked "as" casts Bulk cleanups across all 12 tools/.ts: - Every handler now returns toMcpResult(data) or toMcpText(text) - Open-coded "typeof obj === 'object' && 'error' in obj" in remote_agents.ts replaced with isApiError(v) - Extracted initialCanvasPosition() helper out of handleCreateWorkspace; explains why random seeding exists - Added runtime/workspace_dir/workspace_access to create_workspace zod schema (previously accepted by handler but hidden from clients) src/index.ts: - Replaced "export from" with explicit named re-exports so the public surface is auditable and future name collisions fail loudly Tests: - createServer() smoke test that records every srv.tool(...) call and asserts 87 registered tools unique by name. Catches future PRs that forget to wire a registerXxxTools(srv). Docs: - Fix broken relative links in sdk/python/molecule_agent/README.md (was ../../examples/ from inside sdk/python/, should be ../examples/) - Update stale "61 tools" -> "87 tools" in CLAUDE.md + main() log Verification: - npm run build clean - npx jest -> 97/97 passed (was 96; +1 smoke test) - grep "content: [{ type: \"text\" as const" src/tools/ -> 0 matches - No file over 216 lines Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>		2026-04-13 14:26:17 -07:00

Molecule AI MCP Server

MCP server that exposes Molecule AI platform operations as tools for AI coding agents.

20 Tools Available

Tool	Description
`list_workspaces`	List all workspaces with status and skills
`create_workspace`	Create a new workspace (with optional template)
`get_workspace`	Get workspace details
`delete_workspace`	Delete workspace (cascades to children)
`restart_workspace`	Restart offline/failed workspace
`chat_with_agent`	Send message and get AI response
`assign_agent`	Assign model to workspace
`set_secret`	Set API key or env var
`list_secrets`	List secret keys (no values)
`list_files`	List workspace config files
`read_file`	Read a config file
`write_file`	Create or update a file
`delete_file`	Delete file or folder
`commit_memory`	Store fact (LOCAL/TEAM/GLOBAL)
`search_memory`	Search workspace memories
`list_templates`	List available templates
`expand_team`	Expand workspace to team
`collapse_team`	Collapse team to single workspace
`list_pending_approvals`	List pending approval requests
`decide_approval`	Approve or deny a request

Phase 30 — Remote agent (SaaS) management

Tools that surface workspaces with runtime='external' (agents that run on machines outside this platform's Docker network and join via HTTP).

Tool	Description
`list_remote_agents`	Filter the workspace list to remote agents only — id / status / url / heartbeat
`get_remote_agent_state`	Lightweight `{status, paused, deleted}` projection — faster than `get_workspace` when you only need lifecycle
`get_remote_agent_setup_command`	Emit a `WORKSPACE_ID=… PLATFORM_URL=… python3 …` bash one-liner an operator can paste into a remote shell
`check_remote_agent_freshness`	Compare `last_heartbeat_at` against a threshold (default 90s) — returns `{fresh, seconds_since_heartbeat}`

Setup

Add to your project's .mcp.json:

{
  "mcpServers": {
    "molecule": {
      "command": "node",
      "args": ["./mcp-server/dist/index.js"],
      "env": {
        "MOLECULE_URL": "http://localhost:8080"
      }
    }
  }
}

Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {

      "command": "node",
      "args": ["./mcp-server/dist/index.js"],
      "env": {
        "MOLECULE_URL": "http://localhost:8080"
      }
    }
  }
}

Codex / OpenCode

Environment Variables

Variable	Default	Description
`MOLECULE_URL`	`http://localhost:8080`	Platform API URL

Examples

You: "Create an SEO agent workspace using the seo-agent template"
Agent: [calls create_workspace with template="seo-agent"]

You: "Set the OpenRouter API key for the SEO workspace"
Agent: [calls set_secret with key="OPENROUTER_API_KEY"]

You: "Ask the SEO agent to audit my homepage"
Agent: [calls chat_with_agent with message="Audit https://example.com for SEO"]

You: "What skills does the coding agent have?"
Agent: [calls get_workspace, reads agent_card.skills]
