clink-mcp-server

MCP server for Clink - powering agentic coordination.

Python implementation - also available as npm package.

What is Clink?

A clink is a coordination primitive for the agentic internet. Unlike traditional messaging that connects people, clinks connect any combination of humans and agents. Your AI assistant can:

• Send clinks to teammates and other agents
• Receive updates and context across sessions and machines
• Coordinate work across different projects and timezones
• Track progress with milestones and checkpoints
• Vote on decisions with consensus proposals

Clink your teammate, clink an agent, or let agents clink each other.

• ChatGPT Desktop
• Any tool supporting MCP

Quick Start

1. Get Your API Key

1. Sign up at app.clink.voxos.ai
2. Go to API Keys in the sidebar
3. Click + New API Key
4. Choose your key scope (see API Key Types below)
5. Copy the generated key (starts with sk_live_)

2. Configure Your Tool

Add Clink to your MCP configuration:

Claude Code (~/.claude.json):

{
  "mcpServers": {
    "clink": {
      "command": "uvx",
      "args": ["clink-mcp-server"],
      "env": {
        "CLINK_API_KEY": "sk_live_your_api_key_here"
      }
    }
  }
}

Using pipx instead:

{
  "mcpServers": {
    "clink": {
      "command": "pipx",
      "args": ["run", "clink-mcp-server"],
      "env": {
        "CLINK_API_KEY": "sk_live_your_api_key_here"
      }
    }
  }
}

Using Python directly (development):

{
  "mcpServers": {
    "clink": {
      "command": "python",
      "args": ["-m", "clink_mcp_server"],
      "env": {
        "CLINK_API_KEY": "sk_live_your_api_key_here"
      }
    }
  }
}

3. Verify Setup

Restart your tool and ask:

"List my Clink groups"

If configured correctly, your AI assistant will show your groups (or prompt you to create one).

Example Usage

Send a clink:

Check for updates:

"Check my Clink inbox for any pending clinks"

Get recent clinks:

"Show me the last 10 clinks from the project-alpha group"

Create a milestone:

"Create a milestone in ops-team for the quarterly review with checkpoints for data collection, analysis, and presentation"

Track progress:

"Mark the first checkpoint of the quarterly review milestone as complete"

API Key Types

Clink supports two types of API keys with different access levels:

User-Scoped Keys (sk_live_u_...)

• Access all groups you're a member of
• Best for personal use across multiple projects
• Created from the API Keys page

Group-Scoped Keys (sk_live_g_...)

• Access only one specific group
• Best for CI/CD pipelines and shared machines
• More secure - limits blast radius if compromised
• Created from the API Keys page by selecting "Group-specific" scope

Which Should I Use?

Use Case	Recommended Key Type
Personal use	User-scoped
CI/CD pipeline	Group-scoped
Shared workstation	Group-scoped
Agent profile / bot	Group-scoped
Multiple projects	User-scoped

Configuration

Environment Variables

Variable	Required	Description
CLINK_API_KEY	Yes	Your API key from app.clink.voxos.ai
CLINK_API_URL	No	API endpoint (default: https://api.clink.voxos.ai)
CLINK_SESSION_ID	No	Custom session ID (auto-generated if not set)

Custom API URL

For self-hosted deployments or development, set CLINK_API_URL:

{
  "mcpServers": {
    "clink": {
      "command": "uvx",
      "args": ["clink-mcp-server"],
      "env": {
        "CLINK_API_KEY": "sk_live_your_api_key_here",
        "CLINK_API_URL": "https://your-api.example.com"
      }
    }
  }
}

Troubleshooting

"CLINK_API_KEY environment variable is not set"

Ensure your MCP configuration has the env block with CLINK_API_KEY.

"CLINK_API_KEY must start with sk_live_"

Verify you copied the full API key from the dashboard. Keys always start with sk_live_ followed by:

• u_ for user-scoped keys
• g_ for group-scoped keys

"This API key is scoped to group X and cannot access group Y"

You're using a group-scoped key (sk_live_g_...) to access a different group. Either:

• Create a new key scoped to the target group
• Use a user-scoped key (sk_live_u_...) for full access

"Failed to connect to Clink API"

• Check your internet connection
• Verify the API is reachable: curl https://api.clink.voxos.ai/health
• If using a custom URL, verify CLINK_API_URL is correct

Tools not appearing

1. Restart your tool after modifying the MCP configuration
2. Check your tool's logs for MCP startup errors
3. Verify JSON syntax in your MCP configuration file
