What is SkillGild?

SkillGild is a marketplace for discovering, publishing and monetizing reusable AI agent skills, developer tools and workflows.

• Developers install hosted skills into the coding agent they already use and call them through MCP.

• Creators apply to publish their own skills and workflows for those agents to use.

• Teams invite members to an organization and share the skills the organization unlocks.

Every developer ends up rebuilding the same prompts, workflows and integrations. On SkillGild, someone who knows the job well builds a skill once, and every agent that needs it can reuse it.

Supported agents

One SkillGild account and one connection work across agents.

Claude Code, Codex, Cursor and Gemini CLI connect through SkillGild's local MCP server. Any other client that can run a local stdio MCP server works too.

What you can do

Install and connect

You set this up once per machine. After that, every skill is available to every connected agent. Full instructions: Connect your agent.

1. Install the SkillGild CLI

The skillgild CLI is both the sign-in tool and the local MCP server your agent talks to. It is a single binary with no dependencies.

macOS and Linux:

curl -fsSL https://raw.githubusercontent.com/SkillGild/skillgild/main/scripts/install-cli.sh | sh

Windows (PowerShell):

irm https://raw.githubusercontent.com/SkillGild/skillgild/main/scripts/install-cli.ps1 | iex

The installers download the latest release for your platform and check it against checksums.txt before installing. You can also download an archive from the releases page and put skillgild on your PATH.

2. Sign in

skillgild login

The CLI opens a device page in your browser. Check that the code matches (for example ABCD-EFGH) and click Approve. A revocable credential is saved to your operating system's credential store, never to a config file. Confirm with:

skillgild status

3. Install a skill

skillgild install brag --agent claude-code

Use --agent codex, cursor, gemini-cli, or shared (the default) to match your client. This example installs Brag, a free skill that turns your project into a short launch video.

4. Register the MCP server with your agent

claude mcp add --scope user skillgild -- $(command -v skillgild) mcp

Guide: Install Claude Code skills

codex mcp add skillgild -- $(command -v skillgild) mcp

Guide: Install Codex skills

gemini mcp add --scope user skillgild $(command -v skillgild) mcp

Guide: Gemini CLI skills

Add this to ~/.cursor/mcp.json, or to .cursor/mcp.json in a project. Replace the path with the output of command -v skillgild:

{
  "mcpServers": {
    "skillgild": {
      "type": "stdio",
      "command": "/absolute/path/to/skillgild",
      "args": ["mcp"]
    }
  }
}

Guide: Cursor MCP setup

Start /absolute/path/to/skillgild mcp as a local stdio MCP server.

Guide: Add skills to a coding agent

Restart or reload your agent session. You should then see the skillgild_search_skills, skillgild_start_session, skillgild_call_tool and skillgild_end_session tools.

Prefer to let your agent do the setup? Paste this into Claude Code, Codex, Cursor or Gemini CLI:

Please set up SkillGild for me by following https://skillgild.dev/docs/quickstart-agents
Explain each step in plain language and ask me before running any command.

The MCP server

skillgild mcp is a local stdio MCP server. It gives your agent five tools:

The source is in cli/ (Go, MIT). Build it with cd cli && go build ./cmd/skillgild, or run it in a container with an API key from your account:

docker build -t skillgild .
docker run -i --rm -e SKILLGILD_API_KEY skillgild

How hosted skills work

1. The wrapper. skillgild install writes a small SKILL.md wrapper into your agent's skills folder. It holds public metadata and tells your agent when to use the skill and how to start it. It contains no private implementation.

2. Access check. When a task matches, your agent starts a session over MCP. SkillGild checks your account, entitlement and allowance first. Only then does it deliver the skill's protected instructions for that session.

3. Hybrid execution. Your agent does the work with its own model and tools, in your project. It calls SkillGild server tools for the private steps and shows you a diff before applying changes.

Protected prompts and server tool code are encrypted at rest and are not included in the installed wrapper. Hosted skills need an internet connection. To understand how this differs from an MCP server or a local skill folder, read Agent skills vs MCP servers and Free GitHub agent skills vs SkillGild.

For creators

Built a workflow that other developers' agents could use? Publish a skill on SkillGild:

1. Sign in with Google or GitHub and apply in Account → Creator studio.

2. Create a skill with a public listing and input schema.

3. Write its protected prompt. It is encrypted when you save it and is never shown to callers.

4. Submit it for review, then ship updates as new versions.

The SkillGild team reviews every creator application and skill. Upcoming creator features, including the creator dashboard, analytics and payouts, are tracked on the roadmap.
