Two ways to govern coding-agent changes in Cursor with signetry-core.

Prerequisite

pip install "signetry-core @ git+https://github.com/Signetry/core@v0.6.0"

Add a .signetry/admission.yaml to your repo declaring allowed/forbidden paths, diff budget, and required checks (a conservative default applies without one).

1. MCP server (recommended)

Cursor speaks MCP. Add Signetry's server so the agent can run admission / verify / provenance itself. Copy mcp.json to .cursor/mcp.json in your project (or merge into your existing one):

{
  "mcpServers": {
    "signetry": {
      "command": "python",
      "args": ["-m", "signetry_core.mcp_server"],
      "env": { "SIGNETRY_MCP_ROOTS": "${workspaceFolder}" }
    }
  }
}

Then the agent can call signetry_admit, signetry_verify, and signetry_provenance. SIGNETRY_MCP_ROOTS scopes the server to your workspace so it can't be pointed at arbitrary host paths.

2. Project rule (defense in depth)

Drop signetry.mdc into .cursor/rules/ so the agent is told to stay within the contract and to run signetry guard before writing forbidden paths. This is advisory (the model may still err) — the durable guard is running Signetry in CI on the PR via the Signetry Admission GitHub Action.

Note: Cursor has no deterministic pre-write hook like Claude Code, so in Cursor the strong enforcement is the CI check on the PR; the MCP tools + rule give the agent an in-editor way to self-check first.

Part of the Signetry platform. Governance logic lives in signetry-core; this integration never reimplements policy and never auto-merges.
