### Description (declared)

# harborrag-mcp-server

Owns the FastMCP transport, pre-execution policy, and durable audit boundary.

## Folder ownership

```

The 11 reader tool implementations, schemas, catalog, and checked dispatcher live
in `harborrag_engine.tools`. Generic contracts live in `harborrag_core`.
`harborrag_runtime.composition.readers` connects the reader backends and owns
their lifecycle. MCP adapts authentication, registration, configuration, and
protocol responses; the optional agent uses the same dispatcher.

## Team deliverables

- The shipped transport exposes the eleven read-only tools documented in
  [MCP Tools](../../docs/users/detailed-guides/mcp-server/README.md):
  evidence search/fetch/context, source discovery, static graph description, bounded
  triplet/subgraph/path traversal, exact graph-node resolution, document
  inventory, and faceted entity ranking.
  Chat and agent are not MCP tools; they are served only through the HarborRAG
  REST API's `/v1/chat/completions` and `/v1/agent/completions` endpoints.
- Every attempt and outcome is durably audited with a principal identifier and
  arguments digest; raw arguments and tokens are never recorded.
- Shared reader execution outcomes are recorded separately by the runtime at
  `~/.harborrag/tool-execution-audi…
