# ammo.tools

> Capture email and webhooks from staging and test environments. Point your SMTP and webhook URLs here; traffic is caught and never reaches real users. Inspect messages, payloads, headers, and attachments. Fetch captures through the API or MCP for test assertions.

## What it is

- [Email capture](https://app.ammo.tools/api/docs/email/): Point staging SMTP at smtp.ammo.tools:587; messages are caught and never delivered onward
- [Webhook capture](https://app.ammo.tools/api/docs/webhooks/): Send webhooks to https://ammo.tools/in/<endpoint_id>/<path>; inspect method, headers, body; replay or forward to localhost
- [API access](https://app.ammo.tools/api/docs/): Fetch captured messages and webhooks from tests; filter by recipient, sender, subject, method, path, time; poll with wait
- [MCP server](https://app.ammo.tools/api/docs/mcp/): Local stdio server lets coding agents read captures with read-only tools
- [Localhost forwarding](https://app.ammo.tools/api/docs/webhooks/): CLI client forwards captured webhooks to a local development server

## Getting started for agents

- [Create an account](https://app.ammo.tools/accounts/signup/) or [sign in](https://app.ammo.tools/accounts/login/)
- Create a project to get an SMTP inbox and a webhook capture URL
- Generate an API key on the project's API keys page; each key is scoped to one environment
- Use Bearer authentication: `Authorization: Bearer ak_live_...`
- [MCP setup](https://app.ammo.tools/api/docs/mcp/): download ammo-mcp.py, configure with env vars AMMO_TOOLS_API_KEY and AMMO_TOOLS_API_BASE_URL (https://app.ammo.tools/api/v1)
- MCP tools: get_identity, list_inboxes, list_messages, get_message, get_message_links, get_message_codes, get_message_checks, compare_messages, list_endpoints, list_requests, get_request
