ApolloMcpServer class final

An MCP server exposing ApolloVM as agent tools over a StreamChannel.

Built on the official dart_mcp SDK: it speaks MCP (initialize / tools/list / tools/call) over any newline-delimited StreamChannel — a stdio channel for local use, or the HTTP/SSE channel adapter for networked use. Each tool runs either in-process or (per McpLimits.isolateTools) inside a killable isolate for a hard timeout.

When a RepositoryAdapter is supplied, the server additionally exposes the workspace/repository tools (apollovm.fs.*, apollovm.search.*, apollovm.code.*, apollovm.git.*), letting an agent read, search, navigate and version-control real files instead of shelling out to POSIX. Wrap the adapter in a PermissionGuard to enforce a RepoConfig (read-only by default). With no adapter, the server stays inline-source-only.
