Postbag

What faahim/postbag MCP server does

faahim/postbag MCP server connects an MCP-compatible agent to the Postbag API, a form backend that routes submissions. Postbag is designed to receive HTML form submissions and direct them to destinations such as email, Telegram, webhooks, partners, or a CRM. The MCP layer makes the API available as agent tools instead of requiring the agent to construct HTTP requests itself.

The server is relevant when an agent needs to inspect or operate Postbag resources through its API. The provided description identifies one MCP tool for every Postbag API operation, so the available operation set follows the API rather than being reduced to a single form-submission action.

Tools and capabilities

The faahim/postbag MCP server provides three categories of capability described in the supplied material:

• One tool for each Postbag API operation.
• A quickstart tool for getting started with the service.
• An explain tool for providing explanations related to the API or its use.

The exact operation names, input schemas, output formats, authentication requirements, and API coverage are not included in the supplied excerpt. Consult the project documentation or package metadata before building workflows that depend on a particular operation.

Postbag itself is described as supporting forms that land in an inbox and can then be routed onward. Its broader product description also refers to grouping forms into a stream, mapping different form fields to a shared shape, and sending that shape to a partner between two dates. The excerpt does not establish whether each of those functions is exposed by a corresponding MCP tool, so they should not be assumed to be available through MCP without checking the API documentation.

Limitations and notes

The provided material does not include installation commands or a configuration reference for faahim/postbag MCP server. It also does not identify a required API key, environment variable, MCP transport, package invocation, or client-specific setup. Those details must be verified from the repository before deployment.

The repository states that the @postbag/mcp client package is licensed under MIT. That package license is distinct from the AGPL-3.0 license applied to the server, dashboard, site, and domain packages listed in the repository. Confirm which package or distribution you are using when reviewing license obligations.

The README identifies the live Postbag service at postbag.dev, with a site, documentation, dashboard, and API at /v1. This establishes the service locations described by the project, but it does not by itself document the MCP server's connection procedure.

For evaluation, start with the quickstart and explain tools, then inspect the operation-specific schemas before asking an agent to perform mutations or connect Postbag routing to another system.
