README

@spacepost/mcp

An MCP server that gives AI assistants the whole SpacePost API: one tool per endpoint of the API reference, generated from the OpenAPI document. New API features become MCP tools automatically. Docs: https://docs.spacepost.dev/tools/mcp/

SpacePost is a Resend-compatible transactional email API on Amazon SES (EU company), with an SMTP relay and this MCP server.

Two ways to use it:

Hosted: https://api.spacepost.dev/mcp (Streamable HTTP) with Authorization: Bearer sp_live_.... Nothing to install.
Local (this package): npx -y @spacepost/mcp, stdio. The spec is bundled, so it starts offline.

Create an API key in the SpacePost dashboard. In the official MCP Registry the server is dev.spacepost/mcp; on npm it is @spacepost/mcp.

Configuration

Env
`SPACEPOST_API_KEY`	Required. The assistant has exactly this key's permissions (`sending_access` keys can only send).
`SPACEPOST_BASE_URL`	Optional, default `https://api.spacepost.dev`
`SPACEPOST_DEFAULT_FROM`	Optional sender (e.g. `Acme <hi@acme.com>`) used when `send_email` has no `from`
`SPACEPOST_READ_ONLY`	`true` = `--read-only`
`SPACEPOST_TOOLSETS`	= `--toolsets`
`SPACEPOST_PERMISSION`	= `--permission`

Flag
`--read-only`	Only tools for GET endpoints
`--toolsets a,b`	Only these API areas (OpenAPI tags): emails, domains, apikeys, webhooks, audiences, contacts, broadcasts, suppressions, tenants
`--permission sending_access`	Only tools a send-only key can use (operations with `x-permission: sending_access`)
`--list-tools`	Print the tools for the given options and exit
`--help`, `--version`

The hosted endpoint takes the same options as query parameters: /mcp?read_only=true&toolsets=emails,domains. It derives the permission filter from the caller's key: sending_access keys see only the sending tools in tools/list. Other tools are not blocked by MCP; calling one goes to the API, which answers restricted_api_key as it does for REST.

# local
