Common questions

Is Mailrith Email Marketing safe?

It passed 2 of 2 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: MAILRITH_API_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.0.1) reached the registry 2 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Mailrith MCP Server

Official MCP server for Mailrith.

The server uses the stable @modelcontextprotocol/sdk package for hosted and stdio transports while preserving Mailrith's generated operation schemas.

Use the remote MCP endpoint at https://api.mailrith.com/mcp for hosted agent integrations, or run the local server from this repo for stdio or self-hosted HTTP use. Claude Desktop and other user-connected remote MCP clients authenticate through Mailrith OAuth. Code-first clients that can safely store credentials may send a workspace API key or OAuth access token as Authorization: Bearer .

Official MCP Registry

The registry metadata in server.json identifies the server as com.mailrith/mailrith. Clients can use the canonical Streamable HTTP endpoint at https://api.mailrith.com/mcp, which authenticates through OAuth, or install the local stdio package from npm. Local installs require a workspace API key in MAILRITH_API_KEY.

The hosted server requests Full Email Marketing Access by default for a general-purpose agent. It covers every public email-marketing operation in the selected workspace, but not billing, team, account-security, credential-reading, or internal administration. The discovery_get_capabilities connection check requests the complete public permission catalog so Mailrith can show every Work Profile and default to Full Email Marketing Access. The user can choose Reporting, another focused Work Profile, or custom permissions instead. OAuth stores only the permissions the user approves, and every tool checks those permissions again when it runs.

MAILRITH_API_KEY="<secret>" pnpm --filter @mailrith/mcp-server exec tsx src/cli.ts --transport stdio

Local stdio reads MAILRITH_API_KEY from the client secret environment. The server rejects credentials passed as command arguments so they do not appear in process listings or shell history. Local stdio stops with a clear setup error when the environment variable is missing because it has no browser-based OAuth flow.

Self-hosted HTTP does not read a process-wide API key. Each client must send its own workspace API key or OAuth access token in the Authorization header. The built-in HTTP listener accepts only 127.0.0.1 or localhost; put a TLS reverse proxy in front of it when another machine needs access.

The default submitted profile exposes a fixed reviewed catalog of focused tools such as:

subscribers_list
broadcasts_create
broadcasts_preflight
broadcasts_schedule
broadcasts_send
sequences_update_status
automations_update_status

Every submitted tool has a human-readable top-level title and annotations.title, a narrow description, exact input and output schemas, explicit safety annotations, and machine-readable operation permissions. Request-body inputs expose their JSON type directly as well as their exact referenced schema so connector review tools can validate them without expanding $ref values first. Tools other than the connection check advertise their exact OAuth permissions. The connection check advertises the complete permission catalog so OAuth can offer every Work Profile; its result still reports the exact permissions granted to the connection. The catalog stays the same for every user so clients can review and select tools reliably. Workspace role, plan, product readiness, and granted permissions are enforced when a tool runs.

Anonymous clients may initialize and list this static catalog so ChatGPT and other hosts can start OAuth linking. Anonymous tool calls never reach the Mailrith product API and return HTTP 401 with a standards-based WWW-Authenticate challenge instead. Authenticated calls that need more permissions return HTTP 403 with the complete replacement permission set. Single-tool responses also include MCP's tool-level OAuth challenge metadata for clients that use it when linking or reconnecting an account. Each anonymous HTTP request accepts one JSON-RPC message. Authenticated requests may batch up to 25 messages. These limits keep discovery and tool responses predictable for every connected workspace.

Automation reads never return saved webhook bearer tokens or custom header values. They return only whether each value is configured. If a client reads an Automation and sends the redacted definition back during an update, Mailrith preserves the existing values unless the client explicitly replaces or removes them. Changing the webhook destination requires new credential values so an old secret cannot be carried to another service.

The package also preserves two explicit compatibility profiles:

compact exposes the earlier seven discovery and routing tools.
custom exposes generated focused tools with caller-selected Work Profile, permission, and read-only filters.

Use these profiles only for local or purpose-built clients. The public ChatGPT/Codex plugin and the Claude Connector use the fixed submitted profile at the single /mcp endpoint.

Official Builds And Forks

Modified public versions must use distinct package, registry, plugin, and service names and clearly say that they are unofficial. See the Mailrith Trademark And Unofficial Fork Policy.
