skill + mcp

Crumbs for AI coding assistants

The skill teaches your agent which watcher answers which question. The MCP server lets it read the running app. One command in your project installs the skill.

npx skills add anilcancakir/ai --skill crumbs

run in your project other editor

works with

  • Claude Code
  • Cursor
  • OpenCode
  • VS Code Copilot
  • Codex CLI

Three pieces, one outcome.

The skill shapes what your agent writes, the MCP server acts on the project and llms.txt fills the gaps.

  • Skill

    edit time

    Teaches your agent which watcher answers which question before it reads a single record.

    See the install paths

  • MCP server

    runtime

    Lets your agent read the running app's requests, logs, exceptions and queries over a local stdio server.

    Connect a client

  • llms.txt

    on demand

    A plain-text map of every docs page, for agents that read it once and keep it in context.

    Open llms.txt

Three paths. Pick one for your editor.

Each path covers this skill; the plugin and the installer cover the whole registry.

  • Claude Code plugin

    Adds the registry as a marketplace, then installs its plugin.

    # add the marketplace

    /plugin marketplace add anilcancakir/ai

    # install the plugin

    /plugin install anilcancakir@anilcancakir-marketplace

    Installs every skill in the registry, not only this one.

  • npx skills recommended

    The universal CLI. It works with the editors the skills package supports.

    # this project

    npx skills add anilcancakir/ai --skill crumbs

    # every project

    npx skills add anilcancakir/ai --skill crumbs -g

    The same command the landing page shows.

  • Universal installer

    Detects every supported editor and sets each one up the way it supports: skills, rules, commands or printed steps. It also adds the docs MCP server config.

    # clone and run

    git clone https://github.com/anilcancakir/ai.git && cd ai && bash scripts/install.sh --global --with-mcp

    Covers the whole registry, not only this skill.

Connect the MCP server.

One local server, six clients. Pick yours and paste the config.

Frequently asked

Do I need both the skill and the MCP server?

No. The skill works alone and covers the conventions. The MCP server adds live tools while the agent works. Use both for the best result.

Which AI coding assistants are supported?

The skill installs into Claude Code, Cursor, OpenCode, VS Code Copilot and Codex CLI. Any client that speaks MCP over HTTP or stdio can use the server.

Does Crumbs need an account or a key?

No. Nothing on this page needs an account. An endpoint marked as a placeholder can still change.

Where do I report a mistake?

Open an issue on the Crumbs repository on GitHub with the prompt, what your agent wrote and the docs page that says otherwise.
