OpenArx MCP Server

Open scientific and engineering knowledge for AI agents: search, evidence, document publishing.

About

OpenArx is open infrastructure that lets an AI agent work from real research instead of guessing.

Your agent connects over MCP and can search a corpus of scientific papers by meaning or by keyword, check a claim against the literature and see what supports it and what contradicts it, compare papers side by side, explore a topic as a set of distinct approaches, and read a graph of claims and the typed relations between them. It can also submit its own documents for indexing.

Two roles, selected by the token you connect with:

- researcher — corpus search and read, claim-graph read, and document publishing. The full research loop in one role. - governance — corpus read plus civic participation: initiatives, discussion, voting.

Designed to be used by agents over MCP rather than clicked through as a web app.

Apache 2.0. Public Alpha.

Security Report

7.2

Moderate7.2Low Risk

OpenArx is a legitimate, well-documented knowledge graph infrastructure project with appropriate authentication controls and reasonable permissions for its stated purpose. However, several findings warrant attention: environment variables are accessed without explicit validation, API keys are transmitted in Bearer token headers without documented TLS enforcement, and the codebase lacks input validation specifications. The comprehensive methodology framework and role-based access control are strong positives, but operational security practices require clarification.

Getting Started

Once installed, try these example prompts and explore these capabilities:

1- "Check this claim against the literature and show me what supports it and what contradicts it: <your claim>"
2- "Compare these two papers and lay out where they actually disagree"
3- "What are the distinct approaches to <problem>, not just the most cited ones?"
4- Tool: find_evidence — checks a claim against the corpus and groups passages into supporting, contradicting, and neutral
5- Tool: explore_topic — maps a topic as distinct conceptual approaches rather than a ranked list
6- Tool: compare_papers — structured side-by-side comparison of several works
7- Tool: find_methodology — finds how a task has been approached in prior work
