Agent tools

MCP

Demo-ready MCP support is shown here as an intended capability for agents that need focused context. The examples use seeded incidents only; no live setup happens from this page.

Tool surface preview

Each tool returns a narrow slice of the same context shown in the demo endpoint, so an agent can move from an incident list to a manifest, then into the smallest useful section.

intended capability

Connect your agent

Add the Errorcore MCP server to your agent client, then a scoped key authorizes the tools below. The key carries read-only scopes and reads return scrubbed fields only.
