1. Open https://claude.ai/directory/connectors/contracko, choose Connect to Claude and sign in to Contracko.
2. On Pro and above you can also install the Contracko plugin (Customize, Plugins) for the four contract skills, then connect from its Connectors tab.

The directory connector works on every Claude plan, including Free. On Team and Enterprise, an Owner enables it first. Once connected on web or desktop, it also works in the Claude mobile app.

Added Contracko as a custom connector before? Remove that one, or you will see every tool twice.

On the Free plan you can still add the skills by hand: download them from Releases and upload each one under Customize, Skills.

Signed in with your Claude account? A connector added in Claude is already available here.

For the skills, install the plugin, which also registers the connection:

/plugin marketplace add https://github.com/contracko/contracko-skills.git
/plugin install contracko@contracko

Paste that full GitHub address (not a short owner/repo name). Then run /mcp and sign in in the browser.

Using an API key without the plugin? Run this only if claude mcp list shows no Contracko entry:

claude mcp add --transport http contracko https://app.contracko.com/mcp

If you installed the older contracko-skills plugin, remove that plugin and install contracko@contracko after updating the marketplace. The GitHub repository remains contracko/contracko-skills; the MCP connection remains contracko.

1. In the workspace, go to Settings → Plugins → Import marketplace and enter contracko/contracko-skills.
2. Turn on Developer mode.
3. Go to Settings → Apps → Create and paste https://app.contracko.com/mcp.
4. Sign in in the browser that opens.

ChatGPT has no settings file for this. Use the screens above.

1. Open grok.com/connectors.
2. Add https://app.contracko.com/mcp.
3. Sign in in the browser that opens.

For Grok in the terminal, see Any other assistant below.

npx skills@latest add contracko/contracko-skills
codex mcp add contracko --url https://app.contracko.com/mcp
codex mcp login contracko

Sign in in the browser that opens.

This repository includes a Cursor plugin manifest at .cursor-plugin/plugin.json. It bundles the four existing skills and the MCP connection in mcp.json; no API key is included. The plugin is not yet listed in the public Cursor Marketplace.

To test the plugin locally, clone this repository into ~/.cursor/plugins/local/contracko-skills, reload Cursor, and check Customize for the skills and MCP server. Connect Contracko and complete OAuth in the browser. Approve Read by default and Write only when needed. If you already added the same server manually, use one connection rather than enabling both.

For manual installation without the plugin:

npx skills@latest add contracko/contracko-skills

Then add this to .cursor/mcp.json in your project (create the file if it is not there):

{ "mcpServers": { "contracko": { "url": "https://app.contracko.com/mcp" } } }

Restart Cursor if it does not pick up the connection, then sign in in the browser.

npx skills@latest add contracko/contracko-skills

Then open the Cline panel, go to the Configure tab, and add this to the MCP settings JSON (the CLI reads ~/.cline/mcp.json):

{ "mcpServers": { "contracko": { "type": "streamableHttp", "url": "https://app.contracko.com/mcp" } } }

Sign in in the browser that opens. Set "type": "streamableHttp", because leaving it out falls back to the older SSE transport.

npx skills@latest add contracko/contracko-skills

Then add this to .vscode/mcp.json in your project:

{ "servers": { "contracko": { "type": "http", "url": "https://app.contracko.com/mcp" } } }

Sign in in the browser that opens.

npx skills@latest add contracko/contracko-skills

Then add this to ~/.gemini/settings.json:

{ "mcpServers": { "contracko": { "httpUrl": "https://app.contracko.com/mcp" } } }

Sign in in the browser that opens.

For the thin wrapper, download contracko-openclaw.zip, extract it, and install the directory through OpenClaw's normal bundle flow. The archive contains the four skills only. It does not register or authenticate an MCP server.

For a skills-only install, run npx skills@latest add contracko/contracko-skills.

If you already have the skills, use the native setup below. Check for an existing contracko entry first and do not add a second connection:

openclaw mcp set contracko '{"url":"https://app.contracko.com/mcp","transport":"streamable-http"}'
openclaw mcp configure contracko --auth oauth
openclaw mcp login contracko

Run those commands only after explicitly approving the new central entry. Sign in in the browser that opens and choose Read or Write scopes yourself.

For the thin wrapper, download contracko-hermes.zip, extract it, and install the directory through Hermes's normal plugin flow. Review and enable the package explicitly. The archive contains the four skills only. It does not write MCP configuration or credentials.

For a skills-only install, run npx skills@latest add contracko/contracko-skills.

If you already have the skills, check ~/.hermes/config.yaml for an existing mcp_servers.contracko entry first. If none exists, explicitly approve adding this entry while preserving the rest of the file:

mcp_servers:
  contracko:
    url: "https://app.contracko.com/mcp"
    auth: oauth

Run hermes mcp login contracko and sign in in the browser. Choose Read or Write scopes yourself.

These clients spawn a local process instead of opening the HTTP endpoint themselves:

npx -y @contracko/mcp

That package only launches the hosted server at https://app.contracko.com/mcp. It is not a second MCP implementation. Skills still install with npx skills add https://contracko.com.

Paste this into the assistant and let it follow the file:

Fetch and follow https://contracko.com/mcp/install/prompt.md

If you are adding the connection yourself, the address is still https://app.contracko.com/mcp. Sign in in a browser. Do not add Contracko twice if it is already connected.
