history

Project history and usage

mcp-publisher is the official CLI used to publish server metadata to the Model Context Protocol Registry. It lives in the modelcontextprotocol/registry repository alongside the registry service and documentation.

Project history

The registry repository was created in February 2025 as the official home for a community-driven registry service for MCP servers. The README describes the registry as an app-store-like list of MCP servers for clients, while the `cmd/publisher` tree contains the publishing tool.

The registry README records a preview launch on September 8, 2025 and an API freeze for v0.1 on October 24, 2025. The publisher CLI is central to that preview-era workflow because the registry hosts metadata rather than package artifacts, so server authors publish their package elsewhere and then submit a `server.json` manifest.

Adoption history

The official quickstart documents installing `mcp-publisher` via prebuilt release archives or Homebrew, then using `mcp-publisher init`, `login`, and `publish`. That made Homebrew packaging part of the official cross-platform installation story rather than a third-party convenience only.

GitHub repository metadata showed thousands of stars and hundreds of forks by July 2026. Adoption is tied to registry adoption: the more MCP clients and directories rely on canonical server metadata, the more server authors need the publisher CLI in release automation and local publishing workflows.

How it is used

A typical publishing flow starts by adding package ownership metadata, publishing the actual artifact to a registry such as npm, installing `mcp-publisher`, generating or editing `server.json`, authenticating with the registry, and running `mcp-publisher publish`.

The official docs describe GitHub, DNS, and HTTP authentication methods. They also show that `server.json` contains the server name, repository URL, package identifiers, transport type, version, and environment-variable declarations.

Why package nerds care

mcp-publisher is package-nerd infrastructure: it connects language package registries, source repositories, ownership verification, and MCP client discovery. The CLI gives MCP packages a metadata publishing path without making the MCP Registry host the packages themselves.

Its Homebrew formula is notable because registry publishing is often part of release engineering. A stable system-package install lets maintainers call `mcp-publisher` from shell scripts or CI images without relying on a particular language toolchain.

security posture

No protected-tool coverage found yet

No matching local secret-handling manifest was found for mcp-publisher. Nucleus package metadata is still published here so future coverage has a stable package URL.

Install behavior

  • No Homebrew bottle metadata was recorded.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
