agentmail-toolkit
Add AgentMail tools to agent frameworks with the TypeScript or Python AgentMail Toolkit. Use for Vercel AI SDK, LangChain, OpenAI Agents SDK, LiveKit Agents, or MCP adapters; do not use for direct mailbox operations, raw SDK implementation, CLI usage, or MCP client setup.
Install
With your agent
Install OMGSkills skill "agentmail-to/agentmail-plugins:skills/agentmail-toolkit" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.
Manual command
git clone https://github.com/agentmail-to/agentmail-plugins /tmp/agentmail-plugins && ln -s /tmp/agentmail-plugins/skills/agentmail-toolkit ~/.claude/skills/agentmail-toolkitFrom README
AgentMail Toolkit the toolkit for the selected language and set AGENTMAILAPIKEY. The TypeScript and Python packages can expose different tool sets and can release on different schedules. Discover the installed package's tool catalog at runtime instead of trusting a hardcoded list: TypeScript Vercel AI SDK LangChain MCP server tools Each tool provides a name, title, description, input schema, output schema, callback, and complete annotations for registration on your own MCP server. On a successful call the MCP adapter returns structuredContent (validated against the output schema) alongside the JSON text block; on failure it returns an isError result. The Python package does not ship an MCP adapter. Existing client The toolkit constructor takes an existing SDK client as its only argument — it does not accept an { apiKey } options object directly. Construct the SDK client first, then pass it in.
