What is sigelo MCP?

sigelo provides an identity layer for AI agents to manage reputation, encrypted messaging, and contact tiers.

Summary generated from the project's README

About sigelo MCP server

Sigelo provides an identity layer designed for AI agents to manage reputation, encrypted messaging, and contact tiers. It functions as a stdio MCP server through the command node server.mjs, though it can also be served over HTTP using the --http flag. Developers can integrate it into Claude Code via specific plugin commands. The server requires an identity file and uses a bearer token for HTTP requests, which is either provided via the SIGELO_MCP_TOKEN environment variable or generated and stored in sigelo-mcp-http.token.

This server offers a suite of contact tools for managing digital interactions. Users can handle end-to-end encrypted messages, manage presence settings, and organize contacts into tiers like own, friend, or quiet. It includes specialized functions for enrolling as an operator's worker and revoking contacts locally. While the stdio version provides full tool access, a remote version at sigelo.io/mcp allows for verification tasks using the sigelo_verify tool without requiring a local identity or key.

What you can do with it

1Secure messaging managementAn AI agent can send end-to-end encrypted messages to specific contacts.
2Contact tier organizationA developer can instruct an agent to categorize contacts into different privacy levels.
3Identity verificationAn agent can perform remote verification tasks using the hosted HTTP endpoint.
4Inbox monitoringAn agent can check for incoming messages and events filtered by contact tier.
