What it does
External Agents is an agent skill from BuilderIO/agent-native. Connect external agents and MCP hosts (Claude, Claude Desktop, Claude Code, ChatGPT custom MCP apps, Codex, Cursor, Claude Cowork, VS Code GitHub Copilot, Goose, Postman, MCPJam) to an agent-native app over MCP, and round-trip artifacts back into the UI with MCP Apps and deep links. Use when adding an action's link builder or mcpApp, wiring the /agent-native/open route, exposing an "ingest" action to MCP/A2A, or scaffolding apps from an external agent.
Its SKILL.md is about 7.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/mcp-apps-embedding.md`).
It sits in Mobile, covering Project scaffolding, API testing and MCP servers. It works with Model Context Protocol, OpenAI, Postman and Visual Studio Code. The repository describes itself as: A framework for building agentic apps.
When your agent uses it
- Adding an actions link builder
- Wiring the /agent-native/open route
- Exposing an ingest action to MCP/A2A
- Scaffolding apps from an external agent
Example prompts
- “ingest”
- “/external-agents”
Requirements
- Node.js
- A credential in A2A_SECRET
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Connect to hosted apps
- Add a link builder to an action
- The /_agent-native/open route
- "Ingest" actions for external agents
- Advanced: local development & manual setup
What it can do on your machine
Read from SKILL.md and the folder at commit e16da0c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npxpnpmcodexcursoropencode
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
dispatch.agent-native.commail.agent-native.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
A2A_SECRETACCESS_TOKENBETTER_AUTH_SECRET
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
External Agents loads about 7.2k tokens when it runs, and up to ~9.6k if it reads all its reference files. Until then it costs about 120 tokens; SKILL.md has 3,602 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 3,602 words (~7,152 tokens).
“An agent-native app is reachable by any MCP-compatible host. Keep setup simple: for workspace or cross-app access, add one remote MCP connector: https://dispatch.agent-native.com/mcp. Dispatch's Agents page controls whether that single connector reaches all apps or only selected apps, and Dispatch…”

Can I use External Agents in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add BuilderIO/agent-native --skill external-agents -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/external-agents, .gemini/skills/external-agents, .github/skills/external-agents and .opencode/skills/external-agents in your project.
What does External Agents need to run?
Going by SKILL.md and its folder, External Agents needs the command-line tools its instructions call (npx, pnpm, codex, cursor and opencode) and credentials named A2A_SECRET, ACCESS_TOKEN and BETTER_AUTH_SECRET. Our summary lists: Node.js; A credential in A2A_SECRET.
Does External Agents access the network?
SKILL.md names 2 domains. In commands or code: dispatch.agent-native.com and mail.agent-native.com; the agent is likely to contact these when it follows the instructions. This is read from the text; nothing was executed.
Is External Agents safe to install?
Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
What licence does External Agents use?
No licence was found for External Agents or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does External Agents use?
About 7.2k tokens (SKILL.md is roughly 29k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 2.4k tokens, read only when the agent opens those files.
