Server-provided instructions

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

Compute critical paths for explicitly provided duration/dependency networks. Use elapsed offsets, not calendar scheduling. Explain that resources and holidays are not modeled. Multiple parallel chains can be critical; one displayed chain is illustrative.

calculate_critical_path — Calculate critical path
Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user wants a critical path calculation, project duration, earliest/latest task starts and finishes, or task slack from explicit durations and dependencies. Accepts one to forty tasks, at most 160 finish-to-start dependencies, and durations with at most three decimal places. Includes parallel critical tasks and a CSV schedule. Does not schedule calendar dates, generate Gantt charts, account for resources or holidays, or infer missing task durations.

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 pathline-project-planner-mcp https://critical-path.zovo.one/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 pathline-project-planner-mcp --url https://critical-path.zovo.one/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable pathline-project-planner-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "pathline-project-planner-mcp": {
      "url": "https://critical-path.zovo.one/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "pathline-project-planner-mcp": {
      "type": "streamableHttp",
      "url": "https://critical-path.zovo.one/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start pathline-project-planner-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "pathline-project-planner-mcp": {
      "type": "http",
      "url": "https://critical-path.zovo.one/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 pathline-project-planner-mcp https://critical-path.zovo.one/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": {

      "url": "https://critical-path.zovo.one/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": {
    "pathline-project-planner-mcp": {
      "serverUrl": "https://critical-path.zovo.one/mcp"
