What is octoquery AGENTS.md?

Project instructions for OctoQuery, a NestJS service that lets an MCP client query configured databases and receive rows as JSON. MCP is a standard way for AI tools to call external services; the project supports databases such as PostgreSQL, MySQL, MariaDB, and SQL Server.

Use them when developing, testing, linting, or running OctoQuery, including its local demo databases and OAuth-protected MCP endpoint.

They give an agent the repository layout, setup commands, testing requirements, and security model needed to work on the service safely. They also explain how its database tools and demo environment are organized.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00671	$0.00671
Opus 5.5	$0.00268	$0.00268

Security

Grade A, and why

octoquery AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

OctoQuery — agent guide

OctoQuery is a NestJS service exposing an MCP (Model Context Protocol) server over Streamable HTTP at /mcp. Each PostgreSQL database configured in mcp-sql-tools.json is exposed as one MCP tool that accepts a single query string and returns rows as JSON.

Layout

src/mcp/ — MCP controller, server service, SQL tool handler, lazy database connections
src/auth/ — OAuth 2.0 resource-server guard and RFC 9728 metadata endpoint
mcp-sql-tools.example.json — template for the (gitignored) mcp-sql-tools.json tool configuration
demo/ — Docker Compose playground: seeded demo databases — e-commerce (PostgreSQL), blog (MySQL), library (MariaDB), and helpdesk (SQL Server)

Commands

make run — start the service in watch mode (make help lists all targets)
make test — integration tests (Jest + Testcontainers; requires Docker)
make lint / make lint-fix — Biome + TypeScript checks
make demo-up / make demo-down — start/stop the demo databases
make demo-psql — psql shell into the demo e-commerce database (PostgreSQL)
make demo-mysql — mysql shell into the demo blog database (MySQL)
make demo-mariadb — mariadb shell into the demo library database (MariaDB)
make demo-mssql — sqlcmd shell into the demo helpdesk database (SQL Server)
make mcp-inspector — MCP Inspector for manual testing
