FAQ

Is the Brunosan Arxiv MCP server down right now?

As of 2026-10-25 06:58 UTC, the Brunosan Arxiv MCP server is up with a Glimind reliability score of 78/100 (grade B). Over the last 30 days it answered 99.6% of Glimind's liveness checks. It had 17 outages in 90 days, with a median recovery of 7 minutes.

How many tools does Brunosan Arxiv MCP server provide?

Brunosan Arxiv MCP server advertises 16 tools, including arxiv_author_papers, arxiv_citation_network, arxiv_co_occurrence, arxiv_entity_trend, arxiv_get_paper.

How do I install Brunosan Arxiv MCP server?

Point your MCP client at this streamable-http endpoint: https://arxiv.mcp.brunosan.de/mcp

Is the Brunosan Arxiv MCP server safe to connect to an AI agent?

Glimind scanned all 16 tool definitions for tool-poisoning patterns — hidden or invisible characters, instructions that override the model, concealment from the user, requests to read credential or MCP config files, conversation exfiltration and cross-tool shadowing — and found none. This checks what the server tells the model, not what its code does; review the source before granting access to sensitive data.
