Overview

AI-generated overview

Lets an assistant create and manage Klaviyo email campaigns, lists, and marketing automation through the Klaviyo API.

What you can do
This server exposes Klaviyo's marketing API as MCP tools, so an assistant can create and manage email campaigns, subscriber lists, and marketing automation flows. It is generated from the upstream OpenAPI specification, so the full set of API endpoints is exposed as tools, with request validation and configurable retries. It runs locally as a standalone Python package.
When to use it
Worth adding when an assistant needs to work with Klaviyo marketing data or operations, such as drafting campaigns, managing lists, or adjusting automation, without leaving the chat client. Not useful if you do not use Klaviyo.
Requirements
A local Python runtime (Python 3.11+); the package is run with uvx or pip, or as a Docker image. Klaviyo API credentials are required, though the manifest declares no environment variables or headers; the server's own README documents credential setup. Network access to the Klaviyo API.
Before you install
The server acts on a live Klaviyo account: tools can create and change campaigns, lists, and automation, and may send email to real recipients. Credentials for the Klaviyo API are needed and should be scoped and stored carefully. The manifest declares no authentication or environment variables, so verify how credentials are supplied before installing.

Installation

In SourceWeft

  1. Open Klaviyo in the dashboard and add it to a workspace.
  2. 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.

Other MCP clients

Follow the launch instructions in the repository.

MCP servers that connect AI agents to real-world APIs. Each server is a standalone Python package — generated from the upstream OpenAPI spec using MCP Blacksmith and tested against the live API before release. Hosted on MCP Armory or run independently.

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.

bash
# With uvx (no install needed)uvx mcparmory-github
# With pippip install mcparmory-githubmcparmory-github

MCP client configuration (Claude Desktop, Cursor, Codex, Claude Code):

json
{  "mcpServers": {    "github": {      "command": "uvx",      "args": ["mcparmory-github"],      "env": {        "BEARER_TOKEN": "ghp_your_token_here"      }    }  }}

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:

  1. Parses an OpenAPI specification
  2. Transforms operations through LLM-driven passes (naming, parameter filtering, enhancement, classification)
  3. Generates a complete MCP server with auth, models, validation, and configuration
  4. Tests every tool against the live API using an autonomous agent
  5. 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.

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.

  • Reached in the last 30 days25 pts

    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.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
