Cline

Cline supports MCP servers via its VS Code extension settings UI and project-level rules via .clinerules.

Setup

kcp-harness integrate cline

This generates:

cline-mcp-snippet.json (not committed)

Add this via Cline sidebar > MCP Servers tab > gear icon:

{
  "kcp-harness": {
    "command": "npx",
    "args": ["kcp-harness", "serve"],
    "disabled": false,
    "autoApprove": [
      "kcp_plan",
      "kcp_trace",
      "harness_status",
      "harness_session",
      "harness_budget",
      "harness_temporal_check"
    ]
  }
}

.clinerules (committed)

Governance rules for Cline, including governed paths and mandatory tool usage.

Auto-Approve

The autoApprove list lets Cline call read-only governance tools without a confirmation prompt:

Tool	Auto-approved	Why
kcp_plan	Yes	Read-only plan inspection
kcp_trace	Yes	Read-only decision trace
harness_status	Yes	Read-only status check
harness_budget	Yes	Read-only budget query
harness_temporal_check	Yes	Read-only drift check
kcp_load	No	Loads content — requires approval

This balances governance visibility (the agent can freely inspect plans and traces) with content access control (loading actual content requires human approval).
