Liminal MCP

Liminal MCP provides a shared intelligence workspace for complex research and reasoning tasks. It allows agents to break down questions, check capabilities, find saved work, and receive grounded answers with visible sources and reasoning steps. The server supports cross-session handoffs, context compression, and tool delegation, enabling continuous work without rebuilding context.

Server-provided instructions

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

Liminal keeps your work, sources and handoffs, shared with the Liminal app. Short or direct task: use at most ONE Liminal call, or none. - focus(text=<URL or text>, task=...): instead of opening any page, file or log over 8,000 characters; answer from the returned verbatim passages. - research: a web research question answered with cited findings. - solve: ambiguous, consequential or multi-step decisions; it never claims a write executed. - read: results and sources you already have. - handoff: to continue earlier work call handoff(action="resume", subject=<name>) once; it returns the saved state. To pass work on call handoff(action="create", subject=..., task=..., session_state=<what is done and found>, evidence=...) once. One call each side; no extra notes, list or read. get_capabilities lists every tool; all are callable by name.

90-day uptime

A lightweight connection check about every six hours, sampled on hosts with many listings. It shows the server answered, not that its tools work.

Too few checks for a percentage yet (1 of 1 answered).

30-day availability

Aggregated from read-only remote checks; this is not a tool-execution or security guarantee.

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 liminal-mcp https://liminality.physea.ai/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 liminal-mcp --url https://liminality.physea.ai/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable liminal-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "liminal-mcp": {
      "url": "https://liminality.physea.ai/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "liminal-mcp": {
      "type": "streamableHttp",
      "url": "https://liminality.physea.ai/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start liminal-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "liminal-mcp": {
      "type": "http",
      "url": "https://liminality.physea.ai/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 liminal-mcp https://liminality.physea.ai/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://liminality.physea.ai/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": {
    "liminal-mcp": {
      "serverUrl": "https://liminality.physea.ai/mcp"
    }
  }
