pmcp

Use the skills your packages already ship, and keep your AI tools' project configuration in one place.

pmcp discovers SKILL.md documents in installed packages, workspace packages and plugin marketplaces. Your AI tool can search the catalog and open a skill when it needs one, without loading the entire catalog into each conversation.

Claude Code, Codex, Gemini CLI, Grok Build and Antigravity keep their native model calls, account login and permission controls. pmcp supplies skills, projects shared configuration into their native formats, and optionally provides a local mailbox for exchanging messages.

Get started

Requires Node.js 22 or later, or Bun 1.3 or later.

Install pmcp in your project:

npm install --save-dev @modootoday/pmcp

For Claude Code, register the MCP server from the project directory:

claude mcp add pmcp -- npx @modootoday/pmcp serve

Other MCP hosts can use a stdio entry:

{
  "mcpServers": {
    "pmcp": {
      "command": "npx",
      "args": ["@modootoday/pmcp", "serve"]
    }
  }
}

Restart or reconnect your tool's MCP connection after changing its configuration. Ask your tool to find a skill relevant to your task and open the result. Local skill discovery and reading require no pmcp login.

Native plugins and free library skills

The public GitHub repository is also a marketplace. Choose individual library major lines; adding the marketplace does not activate its entire catalog. For example, install the TypeScript 5 instructions with your native manager:

claude plugin marketplace add modootoday/pmcp
claude plugin install typescript-5@pmcp
claude plugin install pmcp@pmcp

codex plugin marketplace add modootoday/pmcp
codex plugin add typescript-5@pmcp
codex plugin add pmcp@pmcp

Grok supports the same marketplace with grok plugin marketplace add modootoday/pmcp and grok plugin install typescript-5@pmcp. The separate pmcp plugin adds the PMCP MCP bridge. Gemini can install that bridge with gemini extensions install https://github.com/modootoday/pmcp. Native confirmation and runtime provider login remain with each tool.

Since 0.14.0, the CLI bundles the free catalog and can export one plugin for Claude, Codex, Gemini, Grok or Antigravity:

pmcp marketplace list
pmcp marketplace export typescript-5 --runtime agy --output ./typescript-plugin
agy plugin install ./typescript-plugin

The marketplace export command, bundled catalog and anonymous install provider are included in npm 0.14.0. GitHub native marketplace installation and the website's free archives are available independently. See the skills guide for layouts, runtime-specific formats and version selection.

To include your workspace's own skills, create pmcp.toml at the project root:

[catalog]
workspaces = ["."]

Run npx @modootoday/pmcp list to see the local catalog. Paths in the configuration resolve relative to pmcp.toml; pmcp searches for this file above the working directory.

Share configuration across your tools

Declare your tools and MCP servers in the same pmcp.toml:

[targets]
tools = ["claude", "codex", "gemini", "grok", "antigravity", "opencode"]

[mcp.docs]
url = "https://example.com/mcp"

Replace the example URL with your server, then run:

npx @modootoday/pmcp project
npx @modootoday/pmcp project --check
npx @modootoday/pmcp doctor

project generates native files for the selected tools and records its ownership in pmcp.lock. It preserves unrelated settings and refuses conflicting unmanaged entries. --check reports drift without writing files. Each runtime retains its own OAuth session.

OpenCode receives project MCP configuration in opencode.json and reads .agents/skills directly. User-only skills stay available through native slash commands while being hidden from automatic skill selection. Its provider and model choices stay in native user configuration. OpenCode mailbox, terminal control and hook enforcement are outside this projection's supported scope.

The configuration guide covers importing existing servers, environment references, shared skills and rules, shell guards and memory metadata.

Manage native terminals

PMCP 0.13.0 or later can show a native main runtime, its worker terminals and a coordination panel in one terminal workspace. The optional harness and TUI need Linux, tmux, util-linux flock, Node.js 22 or later and a working user systemd manager. Provider login, folder trust and tool approvals remain native.

PMCP 0.16.0 adds the numbered runtime picker, worker menu, worker-start and read-only recovery flows below.

npx @modootoday/pmcp --version
npx @modootoday/pmcp harness doctor inspect
npx @modootoday/pmcp tui doctor

On a supported interactive host, open the workspace with:

pmcp

The first launch lists installed native runtimes. Choose a number or accept the default, then confirm the start; q cancels without creating a group. No group or view JSON is required. Later launches reconnect to the workspace created for this project. Native login and folder trust stay with the runtime. Use pmcp tui --runtime codex-cli to choose the main, or set an optional default:

[tui]
runtime = "codex-cli"

Once the workspace is open, press Ctrl-g then n to choose and confirm a worker. The menu releases input control and preserves the current draft. You can also use pmcp tui start-worker --runtime gemini-cli. The existing group keeps its runtime grants and resource bounds. Use pmcp tui recovery to inspect a saved workspace and obtain explicit next commands after an interrupted start. Inspection does not restart a runtime or replay input.

pmcp tui plan previews the settings without starting anything. The terminal workspace guide covers defaults, custom configuration and advanced controls. The native terminal guide explains explicit group and session operations. Views start read only; acquiring control and stopping a runtime are explicit actions. This optional CLI feature does not add execution tools to the MCP server.

Everyday commands

Run these with npx @modootoday/pmcp, or with pmcp when it is on your PATH:

pmcp list
pmcp available
pmcp install --all --dry-run
pmcp install <skill-package> --yes
pmcp sync --dry-run
pmcp validate

available checks catalog packages against your installed dependencies. install and sync use npm, Bun or pnpm and require confirmation before changing your manifest and lockfile. --dry-run previews the work. Use --catalog <file> to read a saved catalog response.

These commands use the bundled public catalog by default. Public installation downloads verified content-only archives without PMCP login. Use --provider hosted or an explicit --api for a separately hosted service. CLI discovery includes the free marketplace unless --no-builtin is passed or [catalog] builtin = false is configured. Library APIs keep explicit catalog selection.

pmcp login, whoami and logout manage optional hosted-service login. skills.modoo.today is a separate service built on PMCP. Your runtime's provider login remains with that runtime.

Run pmcp --help or pmcp <command> --help for options. With no command, a supported interactive terminal opens the workspace. Piped launches retain MCP stdio; pmcp serve selects MCP explicitly. Unsupported interactive hosts show help and prerequisite guidance.

Compatibility

Provider authentication, native children and vendor behavior have separate qualification scopes. An installed executable or exported manifest is not proof that every native feature works. Public package CI checks actual packed-archive installation, CLI startup, MCP and SQLite before publication; isolated projects on a host are distinct from Docker and OS qualification.

Guides

Semantic search is optional and requires @huggingface/transformers installed separately. Lexical search works without downloading a model. The mailbox is disabled until explicitly configured.
