A meta harness for research queries

Connect your coding agent to better research tools.

Query search, AI answers, and deep research with citations.

Give your agent research with sources, without leaving your workflow.

Ask a question. Your agent does the research.

Ask in plain language and get a source-backed recommendation.

Prompt

Use Librarium to compare SQLite and Postgres for our team app, with sources.

Illustrative outcome

A recommendation grounded in deployment and concurrency evidence, with links to the sources.

Set it up once.

One install, two ways to work

Install the CLI

The CLI includes the MCP server.

Node.js 22.12+

Install
npm install -g librarium
Install
brew install jkudish/tap/librarium
Configure sources
librarium setup
Preview offline
librarium research "Lisbon or Porto without a car?" --only exa --dry-run --json
Research when ready
librarium research "Lisbon or Porto without a car?" --only exa --json

Previewing makes no provider calls, so it costs nothing. Research calls your providers and bills to your API keys. See costs and limits.

Or let your agent do it

Copy its prompt to install and verify Librarium; install.md has the full instructions.

Confirm when asked; add your provider keys (EXA_API_KEY, TAVILY_API_KEY, PERPLEXITY_API_KEY) as environment variables on the server entry, never in chat text.

Add a custom MCP server called librarium that runs: npx -y librarium@2 mcp

Grok Bot runs the server on its own cloud computer, so it can't use a config file or localhost on your machine.
