# neuron_populate_contacts Enrich existing contacts with additional data from connected messaging channels. Syncs profile information from linked platforms. Agent View of the PolicyLayer registry record for `neuron_populate_contacts`. HTML page: https://policylayer.com/tools/io-github-conquext-neuron/neuron-populate-contacts ## Facts - Tool: `neuron_populate_contacts` - Server: Neuron (`neuron-mcp-server`) — https://policylayer.com/tools/io-github-conquext-neuron.md - Install: `npx -y neuron-mcp-server` - Homepage: https://github.com/conquext/neuron - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server auth posture: open - Server CORS policy: * - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "neuron_populate_contacts", "arguments": {} } } ``` ## Why neuron_populate_contacts is rated Medium This tool modifies contact data by enriching and syncing information from external sources. While the changes are reversible (contacts can be updated or reverted), the operation directly alters stored contact records. It is not merely reading data (which would be Read category) because it explicitly enriches and syncs information. From the tool's own definition: "Tool performs 'Enrich existing contacts with additional data' and 'Syncs profile information' – both indicate modification of contact records." ## Use case AI agents use neuron_populate_contacts to create or update resources in Neuron, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Neuron environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
