What is metabase-mcp AGENTS.md?

A repository guide for a TypeScript server that lets AI assistants access Metabase analytics data. It describes the project structure, commands, configuration, and required authentication.

Use it to build, validate, test, run, or debug the server, and to configure access to Metabase with an API key or user credentials.

It gives developers the practical context needed to work in the repository without first discovering its main files and setup rules.

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	$0.00599	$0.00599
Opus 5.5	$0.00240	$0.00240
Sonnet 5.5	$0.00120	$0.00120
Haiku 4.5	$0.00060	$0.00060

Security

Grade A, and why

metabase-mcp 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.

Project Overview

TypeScript MCP server providing AI assistants with optimized access to Metabase analytics data.

Key Files

src/server.ts - MCP server with tool/resource handlers
src/api.ts - Metabase API client with caching
src/handlers/ - Tool handlers (search, list, retrieve, execute, export, clearCache)
src/types/ - TypeScript definitions
src/config.ts - Environment validation

Commands

# Build
npm run build          # Full build with validation + tests
npm run build:fast     # TypeScript only (dev)

# Quality
npm run validate       # type-check + lint + format check
npm run lint:fix       # Auto-fix lint issues

# Test
npm test               # Run tests
npm run test:coverage  # With 80% threshold

# Run
npm start              # Start server
npm run inspector      # Debug with MCP Inspector

Configuration

# Required (choose one auth method)
METABASE_URL=https://your-instance.com
METABASE_API_KEY=your_key              # Recommended
# OR
[email protected]
METABASE_PASSWORD=password

# Optional
LOG_LEVEL=info                         # debug, info, warn, error, fatal (debug enables pretty JSON)
CACHE_TTL_MS=600000                    # 10 min default

Rules

Code Style

Strict TypeScript (noImplicitAny, noUnusedLocals, noUnusedParameters)
ESLint + Prettier enforced
No emojis in code, docs, or tool descriptions

Testing

Tests in tests/ mirror src/handlers/ structure
Mock API at handler level, not API client level
Do NOT create tests/api.test.ts - API methods tested through handlers
80% coverage threshold enforced

MCP Design Pattern

Never implement the same functionality as both Resource and Tool.
