### Description (declared)

# realy-mcp

An MCP server that answers natural-language questions about **your** database by
composing validated table operations, and returns typed rows plus a reviewable
trace of every step.

You run it. In your environment. Against your database. On your model
credentials. Nothing is sent anywhere you did not configure — see
[docs/THREAT_MODEL.md](docs/THREAT_MODEL.md).

---

## Install

```bash
pip install "realy-mcp[openai,postgres]"
```

Extras select what gets installed: providers (`openai`, `anthropic`, `google`,
`groq`) and the optional DuckDB backend (`duckdb`). PostgreSQL/psycopg is included by default;
`postgres` remains a compatibility extra. Pick only what you use — a
customer on Azure OpenAI never has an Anthropic SDK on disk.

Python 3.10–3.13. The install is a database driver and an SDK; there is no
pandas, no numpy, no ML stack.

## Configure

Create [`realy.toml`] and edit it. An example:

```toml
[connection]
id = "main"
url_env = "REALY_DB_URL"          # env var NAME, not the URL
read_only = true

[[connection.tables]]
name = "claims"
source_table = "v_claims_scoped"  # a view you control
description = "One row per submitted claim. `amount` is USD..."

[model]
provider = "openai"
model = "gpt-4o"
api_key_env = "REALY_MODEL_API_KEY"
base_url = "https://my-azure.openai.azure.com/v1"   # optional
```

Two things to get right:

**Secrets are named, not written.** `url_env` and `api_key_env` hold the *names*
of environment variables. The config file itself contains no credentials, so it
can be committed and reviewed.

**`description` is the highest-value field in the file.** It is what the calling
agent reads to decide whether a question is answerable here, and what stops the
agent guessing at a column's meaning. Write it as if explaining the table to a
new analyst — including the traps ("`paid_amount` is NULL until settlement").

Set up these enviroment variables:

```bash
export REALY_DB_URL='postgresql+psycopg://realy_ro:...@db.internal/warehou…
