Starts the Beamscope MCP server over HTTP.
mix beamscope.mcp
mix beamscope.mcp --port 9877Exposes get_callers, get_callees, find_call_path, search_code as
MCP tools at http://localhost:<port>/mcp, routed through Beamscope.Repo
(backed by Beamscope.Callgraph.Store/Beamscope.Search.Store). Each tool
call takes an explicit repo_path; the graph/search index for that path
is built once (on the first call that needs it) and cached across calls
within this server process's lifetime.
Built directly on Plug + Bandit + Jason (Beamscope.MCP.Protocol/
Beamscope.MCP.Router), not an MCP protocol library — connect an MCP
client to the URL above as a remote HTTP server rather than spawning
this as a stdio subprocess.
