What is influxdb-mcp-server CLAUDE.md?

Project instructions for building, testing, and running an InfluxDB MCP server. InfluxDB is a database commonly used for time-stamped data such as measurements and events.

Installing dependencies, running tests, starting the server, testing with Docker, and debugging protocol messages.

It gives contributors consistent commands, code conventions, error handling guidance, and required configuration details.

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	$0.00813	$0.00813
Opus 5.5	$0.00325	$0.00325
Sonnet 5.5	$0.00163	$0.00163
Haiku 4.5	$0.00081	$0.00081

Security

Grade A, and why

influxdb-mcp-server CLAUDE.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 12d 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.

InfluxDB MCP Server - Guide for Claude

Build & Test Commands

Run all tests: npm test
Run a single test: npm test -- -t "test name" (e.g., npm test -- -t "should list organizations")
Skip integration tests: npm test -- --testPathIgnorePatterns=integration.test.js
Install dependencies: npm install
Start server: INFLUXDB_TOKEN=your_token node src/index.js
Test with Docker: Make sure Docker is running before executing tests
Debug tests: Add DEBUG=mcp:* environment variable for detailed MCP protocol logging

Code Style Guidelines

Language: ES Modules JavaScript with TypeScript types (file extensions: .js)
Testing: Jest with 60-second timeout for Docker operations
Formatting: 2-space indentation
Naming: camelCase for variables/functions, PascalCase for classes
Types: Zod for runtime type validation
Error handling: Try/catch blocks with structured error messages
Imports: ES modules with named imports
Async patterns: Async/await pattern preferred over promises

Environment

Required vars: INFLUXDB_TOKEN (authentication)
Optional vars:
- INFLUXDB_URL (defaults to http://localhost:8086)
- INFLUXDB_ORG (organization name for queries)
- INFLUXDB_BUCKET (default bucket for write-data)
- DEBUG=mcp:* (enables MCP protocol debugging; logs full messages including data)
HTTP transport vars (--http only):
- MCP_HTTP_HOST (bind interface, defaults to 127.0.0.1; same as --host)
- MCP_AUTH_TOKEN (require Authorization: Bearer; mandatory for non-loopback hosts)
- MCP_ALLOWED_HOSTS (comma-separated Host header allowlist)
- MCP_HTTP_ALLOW_UNAUTHENTICATED=true (opt out of the auth requirement off loopback)
- MCP_HTTP_BODY_LIMIT (defaults to 4mb)

Project Structure

src/index.js - CLI entry point; src/server.js - MCP server factory
src/http/app.js - Express app for Streamable HTTP (Host validation, auth, limits)
src/config/ - env.js (InfluxDB env) and http.js (HTTP transport options)
src/utils/ - InfluxDB client, Flux CSV parser, Flux escaping, logging
tests/ - Integration tests using Docker containers, plus Docker-free unit/HTTP tests
direct-tests/ - Handler tests against a Dockerized InfluxDB

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
