Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to mcparmory.com. It runs from a package rather than a hosted endpoint, so there is no endpoint to match against that domain.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

A local MCP server that connects an assistant to the Postmark API for sending, tracking and managing transactional and bulk email.

What you can do: Send transactional and bulk email through Postmark, and manage the messages and templates involved in delivery. Track delivery activity and review the results of sends. Exposes the full set of Postmark API endpoints as tools, with request parameters validated before each call.
When to use it: Useful when an assistant should draft and send email through a Postmark account, or look up delivery and message data, as part of a support, notification or marketing workflow.
Requirements: Runs as a local process on the user's machine, launched with uvx from the PyPI package or with Docker from the published image; Python 3.11+ for the package route. A Postmark account and its API credentials are needed, though the manifest declares no environment variables or headers. Network access to the Postmark API.

Before you install

Sending email is an outward-facing action that reaches real recipients and may incur Postmark costs or affect sender reputation; review before letting an assistant send. Credentials for the Postmark account must be supplied, and message content and recipient data are sent to Postmark.

Installation

In SourceWeft

Open Postmark in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Install & Usage

Every server is a standalone PyPI package (mcparmory-<server-name>). Each server's own README.md has full credential setup and configuration instructions.

# With pippip install mcparmory-githubmcparmory-github

Features

Every server in this registry provides:

Full API coverage — all endpoints from the OpenAPI spec are exposed as MCP tools
Authentication — API key, Bearer token, Basic auth, OAuth2, JWT, OpenID Connect, and mutual TLS
Multi-auth — servers that support multiple auth methods let you configure whichever you prefer
Pydantic validation — request parameters are validated before sending to the API
Resilience — configurable retries with exponential backoff, connection pooling, and timeouts
Response sanitization — optional redaction of sensitive fields from API responses

How servers are generated

Servers are generated by MCP Blacksmith, an automated pipeline that:

Parses an OpenAPI specification
Transforms operations through LLM-driven passes (naming, parameter filtering, enhancement, classification)
Generates a complete MCP server with auth, models, validation, and configuration
Tests every tool against the live API using an autonomous agent
Deploys passing servers to this registry

The generator targets Python 3.11+ and uses FastMCP as the MCP framework.

Contributing

Servers are auto-generated — don't edit server code directly. If you find an issue, open a GitHub Issue describing:

Broken or deprecated endpoints
Missing or incorrect parameters
Authentication problems
Incorrect request/response models

We'll re-generate the affected server with the fix. To request a new server, open an issue with a link to the API's OpenAPI spec or documentation.

License

Each generated server is released under the MIT License. The underlying APIs have their own terms of service — see individual server READMEs for details.

Score

40% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.
Auth declared10 pts
Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
