[Unreleased]

FastMCP exposed the internal Context parameter (ctx) as a required client-facing tool argument on every tool, so MCP clients failed every call with ctx Field required. from __future__ import annotations made FastMCP see the annotation as a string and miss the Context-detection branch; the fix patches __annotations__["ctx"] back to the real Context class before registering each tool. (#7)

Regression test that constructs the server and asserts ctx is absent from every tool's MCP-facing inputSchema while run_sql still requires query.

Single teslamate-mcp console script with stdio, http, gen-token, and list-tools subcommands.
src/teslamate_mcp package using a proper src-layout, distributable via hatchling.
Six MCP prompts for common analyses: battery health, driving summary, charging behaviour, anomalies, weather efficiency, and a quick status report.
Two MCP resources: teslamate://queries (index) and teslamate://queries/{name} (raw SQL per tool).
Context.info/Context.warning streaming from every tool, including elapsed time on run_sql.
/health liveness route and Docker HEALTHCHECK.
Multi-stage Dockerfile producing a slim runtime image with OCI labels.
Release workflow: pushing a v* tag builds and publishes a multi-arch image to GHCR and opens a GitHub release.
GitHub Actions CI: ruff lint/format check, pytest on Python 3.11/3.12/3.13, Docker build smoke test.
pytest suite with testcontainers-backed Postgres for end-to-end coverage of the read-only execution path.

run_sql now runs inside a PostgreSQL READ ONLY transaction with statement_timeout, lock_timeout, and idle_in_transaction_session_timeout enforced via SET LOCAL. When the user omits LIMIT, the query is wrapped in a capped subselect.
get_database_schema reads information_schema at runtime instead of a checked-in JSON snapshot.
Decimal column values are serialised as float so language models can do arithmetic on them.
Bearer-token comparison switched to hmac.compare_digest (timing-safe).
Configuration moved to pydantic-settings with full .env support.

main.py and main_remote.py (replaced by the CLI subcommands).
utils/generate_token.py (replaced by teslamate-mcp gen-token).
data/all_db_info.json (replaced by live introspection).
Direct dependency on the standalone fastmcp PyPI package; the project now uses only the official mcp[cli] SDK.

Previous baseline. See git history for details.
