Construction Intelligence MCP

ProjectService is the governed project-discovery interface for the Construction Intelligence Platform. It reads the canonical ci_market_state table from DuckDB in read-only mode and returns Pydantic business objects rather than DataFrames. Consumers use service methods or MCP tools and do not need SQL.

Install

Python 3.12 or newer is required.

python -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip
python -m pip install -e '.[dev]'

Set the source database for integration tests, the smoke test, and MCP:

export CI_DATABASE=/absolute/path/to/caltrans_pricing.duckdb

The database is always opened read-only; this project does not modify the source DuckDB.

Test and lint

python -m pytest
python -m ruff check .

Tests backed by the actual ci_market_state schema run when CI_DATABASE points to an available file. Otherwise, those integration tests are reported as skipped.

Smoke test

construction-intelligence-mcp smoke-test

The command prints the resolved source table, identifier and description fields, the total project count for Southern California districts 7, 8, 11, and 12, and five sample business objects.

Launch MCP

The default transport is SSE on 0.0.0.0:8000:

construction-intelligence-mcp serve

To select the transport or listener explicitly:

CI_MCP_TRANSPORT=sse CI_MCP_HOST=127.0.0.1 CI_MCP_PORT=8000 construction-intelligence-mcp serve

The MCP tools are search_projects and fetch_project.
