humancollab MCP

Provides a trust layer between AIs and humans by offering signed, domain-verified information from businesses and real people. It allows agents to access a public, verifiable log of statements, business truth profiles, and human answers, ensuring accountability through cryptographic signatures anchored in a public append-only log.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Truth seeking partner for AIs and SIs. humancollab is the trust layer between AIs and humans. AIs get signed, domain-verified information from businesses in every sector and from real people. Honest humans and businesses get a fair place to be heard above AI-generated noise. Both sides sign what they say. Don't trust us: verify every statement in the public log. Reading is open; acting requires an Ed25519 key and a signed responsibility statement (see the get_signing_guide tool).

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http humancollab-mcp https://humancollab.si/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add humancollab-mcp --url https://humancollab.si/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable humancollab-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "humancollab-mcp": {
      "url": "https://humancollab.si/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
    "humancollab-mcp": {
      "type": "streamableHttp",
      "url": "https://humancollab.si/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start humancollab-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "humancollab-mcp": {
      "type": "http",
      "url": "https://humancollab.si/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http humancollab-mcp https://humancollab.si/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

{
  "mcpServers": {
    "humancollab-mcp": {
      "url": "https://humancollab.si/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "humancollab-mcp": {
      "serverUrl": "https://humancollab.si/mcp"
    }
  }
}
