flutterflow-mcp

flutterflow-mcp is an original FlutterFlow MCP server built around a command-palette model.

What Orbit Is

Orbit is different from multi-tool MCP servers by design:

• One primary tool: orbit
• Command palette verbs inside cmd (help, snapshots.create, changeset.apply, etc.)
• SQLite snapshot cache with persisted indices/graphs
• Policy engine (orbit.policy.json + env overrides)
• Transactional ChangeSet flow: new -> add -> preview -> validate -> apply

Features

• Node.js 18+ TypeScript strict implementation
• MCP stdio transport for Claude Desktop/Cursor/Windsurf/Claude Code/Codex
• Separate HTTP health/status/policy service on port 8080
• FlutterFlow API adapter (set FLUTTERFLOW_API_TOKEN for remote reads/writes)
• SQLite snapshot store (files, hashes, symbols, edges)
• Navigation + component usage graph index
• Safe editing policy engine with manual-approval mode
• Orbit schema pack resources:
  • orbit://schema/index
  • orbit://schema/doc/{id}
  • orbit://schema/snippet/{id}

Quick Start

1) Install

npm i

2) Configure env (optional for local startup)

export FLUTTERFLOW_API_TOKEN=your_token_here

Without a token, the MCP server still starts, but commands that call FlutterFlow APIs (for example projects.list, snapshots.create, snapshots.refresh) will return a missing-token error until you set it.

Optional API path overrides:

export FLUTTERFLOW_API_BASE_URL=https://api.flutterflow.io/v2
export FLUTTERFLOW_API_LIST_PROJECTS_PATH=/l/listProjects
export FLUTTERFLOW_API_LIST_PARTITIONED_FILES_PATH=/listPartitionedFileNames
export FLUTTERFLOW_API_PROJECT_YAMLS_PATH=/projectYamls
export FLUTTERFLOW_API_VALIDATE_PROJECT_YAML_PATH=/validateProjectYaml
export FLUTTERFLOW_API_UPDATE_PROJECT_YAML_PATH=/updateProjectByYaml
export FLUTTERFLOW_API_MIN_INTERVAL_MS=1000

3) Run

npm start

This starts:

• MCP server over stdio
• HTTP server on http://localhost:8080

Endpoints:

• GET /health
• GET /status
• GET /policy

If the HTTP port is already in use, Orbit now continues with MCP stdio and logs a warning to stderr. You can disable HTTP endpoints entirely with:

export ORBIT_HTTP_ENABLED=0

MCP Client Setup

Use npm start as your MCP command.

Claude Desktop / Cursor / Windsurf

Use templates/mcp-config.local.json as a base:

{
  "mcpServers": {
    "ff_orbit_mcp": {
      "command": "npm",
      "args": ["start"],
      "cwd": "/absolute/path/to/ff-mcp",
      "env": {
        "FLUTTERFLOW_API_TOKEN": "YOUR_TOKEN"
      }
    }
  }
}

Claude Code

Use project config file .mcp.json (you can copy templates/claude-code.mcp.json):

{
  "mcpServers": {
    "ff_orbit_mcp": {
      "command": "npm",
      "args": ["start"],
      "cwd": "/absolute/path/to/ff-mcp",
      "env": {
        "FLUTTERFLOW_API_TOKEN": "YOUR_TOKEN"
      }
    }
  }
}

Or add it with CLI:

claude mcp add -s project -e FLUTTERFLOW_API_TOKEN=YOUR_TOKEN ff_orbit_mcp -- npm start

Codex (CLI / App)

Option A: add via CLI:

codex mcp add ff_orbit_mcp --env FLUTTERFLOW_API_TOKEN=YOUR_TOKEN -- node /absolute/path/to/ff-mcp/dist/main.js

Build once before using the command above:

npm run build

Option B: add to ~/.codex/config.toml (see templates/codex-config.toml):

[mcp_servers.ff_orbit_mcp]
command = "npm"
args = ["start"]
cwd = "/absolute/path/to/ff-mcp"
env = { FLUTTERFLOW_API_TOKEN = "YOUR_TOKEN" }
enabled = true

High-ROI recipes

• Generate best-practice pages with deterministic recipes (preview-first):
  • orbit({ cmd:"page.scaffold", args:{ name:"login2", recipe:"auth.login", preview:true } })
  • orbit({ cmd:"page.scaffold", args:{ name:"preferences", recipe:"settings.basic", params:{ toggles:["Notifications","Dark mode"] }, apply:true } })
  • orbit({ cmd:"intent.run", args:{ text:"create a list page called products with search", preview:true } })
• Duplicate a widget twice:
  • orbit({ cmd:"widget.duplicate", args:{ nameOrId:"login", nodeId:"id-Text_a", count:2, apply:true } })
• Insert a widget in one call:
  • orbit({ cmd:"widget.insert", args:{ nameOrId:"login", type:"Divider", beforeNodeId:"id-Button_b", apply:true } })
• Batch-update text widgets:
  • orbit({ cmd:"widgets.updateMany", args:{ nameOrId:"login", filter:{ type:"Text" }, set:{ text:"James NC" }, apply:true } })
• Find widgets with one canonical search command:
  • orbit({ cmd:"widgets.find", args:{ nameOrId:"login", type:"TextField", textContains:"Password" } })
• Batch get exact widgets:
  • orbit({ cmd:"widget.getMany", args:{ nameOrId:"login", nodeIds:["id-Text_a","id-Button_b"] } })
• Route a button to another page:
  • orbit({ cmd:"routes.upsert", args:{ nameOrId:"login", nodeId:"id-Button_b", toPageNameOrId:"DailyDashboard", apply:true } })
• Inspect and validate page routes:
  • orbit({ cmd:"routes.listByPage", args:{ nameOrId:"login", direction:"both" } })
  • orbit({ cmd:"routes.validate", args:{ nameOrId:"login", strict:true } })
• Batch move and unwrap widgets:
  • orbit({ cmd:"widget.moveMany", args:{ nameOrId:"login", nodeIds:["id-Text_b","id-Text_c"], afterNodeId:"id-Button_b", apply:true } })
  • orbit({ cmd:"widget.unwrap", args:{ nameOrId:"login", nodeId:"id-Row_wrap", apply:true } })
• List/get widget trigger actions:
  • orbit({ cmd:"widget.action.list", args:{ nameOrId:"login", nodeId:"id-Button_b" } })
  • orbit({ cmd:"widget.action.get", args:{ nameOrId:"login", nodeId:"id-Button_b", trigger:"ON_TAP" } })
• Ensure snapshot freshness before read/write:
  • orbit({ cmd:"snapshots.ensureFresh", args:{ staleMinutes:30 } })
• Use sticky selection in conversational follow-ups:
  • orbit({ cmd:"selection.get" })
  • orbit({ cmd:"intent.run", args:{ text:"unwrap this", apply:true } })
• Safe apply orchestration:
  • orbit({ cmd:"changeset.applySafe", args:{ changesetId:"chg_x", confirm:true } })
• Rollback latest applied changeset:
  • orbit({ cmd:"changeset.rollback", args:{ latestApplied:true, confirm:true, apply:true } })
• Safer page delete flow:
  • orbit({ cmd:"page.preflightDelete", args:{ nameOrId:"login2" } })
  • orbit({ cmd:"page.remove", args:{ nameOrId:"login2", apply:true } })
  • page.remove attempts hard delete first, and can fall back to archive mode if FlutterFlow rejects delete payloads.
• Validate/repair tree integrity:
  • orbit({ cmd:"tree.validate", args:{ nameOrId:"login" } })
  • orbit({ cmd:"tree.repair", args:{ nameOrId:"login", fixOrphans:true, fixMissingNodes:true, apply:true } })

Optional support tools:

• orbit_policy_get
• orbit_policy_set (disabled unless ORBIT_ALLOW_POLICY_WRITE=1)
• orbit_export_changeset

Snapshot Workflow

1. orbit({cmd:"projects.list"})
2. orbit({cmd:"snapshots.create", args:{projectId:"..."}})
3. Query against snapshot id
4. Run snapshots.refresh before sensitive changes to avoid stale decisions (now throttled by default to reduce 429s)

Orbit snapshots are point-in-time and may be stale. When FlutterFlow returns versionInfo (partitionerVersion, projectSchemaFingerprint), Orbit stores it and uses it for smarter incremental refresh decisions. If FlutterFlow is rate-limiting refresh (429), prefer budgeted crawl mode:

• orbit({ cmd:"snapshots.refreshSlow", args:{ passes:4, pauseMs:15000, maxFetch:25, concurrency:1, sleepMs:250 } })
• orbit({ cmd:"snapshots.refresh", args:{ mode:"full", fetchStrategy:"bulk" } }) for low-request full sync attempts
• orbit({ cmd:"snapshots.refresh", args:{ mode:"full", fetchStrategy:"file", maxFetch:5, concurrency:1, sleepMs:1000 } }) for chunked full sync without relisting each pass (chunkedFull defaults to true for full+file)

Safe Editing Workflow

1. changeset.new
2. changeset.add (one or many patches)
3. changeset.preview (diff + risk)
4. changeset.validate (YAML + structure + policy)
5. changeset.apply with confirm:true (includes remote validateProjectYaml checks before push)

If policy requires manual approval, apply is refused and a manual payload is returned.

Policy Engine

Default file: orbit.policy.json

Fields:

• allowProjects
• allowFileKeyPrefixes
• denyFileKeyPrefixes
• maxFilesPerApply
• maxLinesChanged
• requireManualApproval
• allowPlatformConfigEdits
• safeMode: readOnly | guidedWrite | fullWrite

Env overrides:

• ORBIT_POLICY_ALLOW_PROJECTS
• ORBIT_POLICY_ALLOW_FILE_PREFIXES
• ORBIT_POLICY_DENY_FILE_PREFIXES
• ORBIT_POLICY_MAX_FILES_PER_APPLY
• ORBIT_POLICY_MAX_LINES_CHANGED
• ORBIT_POLICY_REQUIRE_MANUAL_APPROVAL
• ORBIT_POLICY_ALLOW_PLATFORM_CONFIG_EDITS
• ORBIT_POLICY_SAFE_MODE
• ORBIT_ALLOW_POLICY_WRITE=1 (to enable orbit_policy_set)

Fly.io Deployment

flyctl launch
flyctl secrets set FLUTTERFLOW_API_TOKEN=your_token_here
flyctl deploy

fly.toml is configured with auto-suspend:

• auto_start_machines = true
• auto_stop_machines = "suspend"
• min_machines_running = 0

Development

npm run build
npm test
npm start

Security Notes

• Keep FLUTTERFLOW_API_TOKEN only in environment variables or secret managers.
• Snapshot DB can include full project YAML and should be treated as sensitive data.
• orbit.policy.json should be code-reviewed because it controls write boundaries.
• Built-in read-only guards deny direct apply for custom code and unlocked lib/main.dart.

FlutterFlow Project APIs Coverage

Orbit supports all currently documented FlutterFlow Project APIs (v2) through the adapter layer:

• POST/GET /l/listProjects
• GET /listPartitionedFileNames
• GET /projectYamls (including projectYamlBytes base64 zip decoding)
• POST /validateProjectYaml
• POST /updateProjectByYaml
