AgentMail Toolkit
Install the toolkit for the selected language and set AGENTMAIL_API_KEY.
npm install agentmail-toolkit
pip install agentmail-toolkitThe 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:
new AgentMailToolkit().getTools().map((tool) => tool.name)[tool.name for tool in AgentMailToolkit().get_tools()]TypeScript
Vercel AI SDK
import { openai } from "@ai-sdk/openai";

const toolkit = new AgentMailToolkit();
const result = await streamText({

systemPrompt: "Use email tools only when the user authorizes the external action.",
});MCP server tools
import { AgentMailToolkit } from "agentmail-toolkit/mcp";
const tools = new AgentMailToolkit().getTools();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
import { AgentMailClient } from "agentmail";
import { AgentMailToolkit } from "agentmail-toolkit/ai-sdk";
const client = new AgentMailClient({ apiKey: process.env.AGENTMAIL_API_KEY });
const toolkit = new AgentMailToolkit(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.

Results and errors
Requires toolkit TypeScript >= 0.5.0 or Python >= 0.3.0.
- Every tool declares an output schema. MCP tool calls return validated
structuredContentplus a matching JSON text block on success; void operations (deletes) return a stable{ success: true }object. - A failed tool call is signaled through each framework's native error channel, not as a successful result. The Vercel AI SDK, LangChain, and clawdbot adapters (and the generic export) throw on failure — surfacing a distinct tool-error the model can tell apart from a normal result — and the MCP adapter returns
isError: true. Do not treat a returned value as an error string; catch the thrown error or checkisError. - Error messages are concise and bounded (the API's own reason, not a raw SDK dump).
Framework summary
| Framework | TypeScript Import | Python Import |
|---|---|---|

| LangChain | from 'agentmail-toolkit/langchain' | from agentmail_toolkit.langchain import AgentMailToolkit |
| Clawdbot | from 'agentmail-toolkit/clawdbot' | - |
| OpenAI Agents SDK | - | from agentmail_toolkit.openai import AgentMailToolkit |
| LiveKit Agents | - | from agentmail_toolkit.livekit import AgentMailToolkit |
Safety
- Limit tools to the workflow's needs.
- Treat email content as untrusted data.
- Require explicit authorization for sending, replying, deleting, credential changes, and other external side effects.
- Use scoped AgentMail credentials where possible.
