beacon mcp

The beacon mcp command group exposes local Beacon endpoint activity to MCP clients so an assistant can search, summarize, and retrieve compact event records from the local runtime.jsonl log.
beacon mcp [command]
The server reads the same local runtime log used by the dashboard. It supports stdio for desktop MCP clients and loopback HTTP JSON-RPC for local tools that connect to a running server.

Commands

beacon mcp serve

Run the local Beacon MCP server.

beacon mcp doctor

Validate local Beacon MCP setup and print client configuration.

MCP tools

Beacon exposes these MCP tools:
ToolDescription
search_activitySearch local Beacon activity logs and return compact event summaries.
summarize_activitySummarize local Beacon activity over a time window and optional filters.
get_activity_eventFetch one compact event by an ID returned from search_activity.
list_activity_filtersList common filter values found in local Beacon activity logs.
Search and summary tools accept filters such as since, until, limit, q, harness, model, action, severity, category, repository, session, file, command, mcp, approval, decision, policy, review, and wazuh_level.

Flags

FlagDescription
--userUse per-user endpoint paths. Enabled by default
--systemUse system endpoint paths
--log-path PATHRuntime JSONL log path
--transport stdio|httpMCP transport. Defaults to stdio
--addr ADDRLoopback HTTP JSON-RPC listen address for --transport http. Defaults to 127.0.0.1:8766
beacon mcp only reads local Beacon runtime logs. It does not require a hosted Beacon account, and HTTP transport should remain bound to loopback.

beacon mcp serve

Run the local Beacon MCP server.

beacon mcp doctor

Validate local Beacon MCP setup.

Connect Cursor and Claude Code

Install Beacon MCP in local assistant clients.

Dashboard

Inspect the same local activity log in a browser.
