exa

exa is an MCP server for Claude Code from jiutuhky/my-super-capsule. Its token cost is not measured, scanned A, original, MIT.

A connection between an AI agent and Exa, a web-search and content-fetching service. It runs locally and requires an Exa API key.

In plain words
What is it for?
Use it when an agent needs web searches, fetched online content, or a research process involving several linked steps.
Why use it?
It gives an agent a way to search the web, retrieve page content, and carry out multi-step research without building those connections from scratch.

MCP server for Claude Code

Written for Claude Code: shipped in a Claude Code plugin. Also seen: listed in a Claude config.

Part of the patent-writer plugin — 2 skills, 1 command, 7 agents, 2 MCP servers shipped together

One of 2 entries in .mcp.json upstream. Installing this one merges just its entry into your config; the other 1 are separate, each on its own page.

Good fit Use it when an agent needs web searches, fetched online content, or a research process involving several linked steps.

Getting it into your agent

Security

Grade A, and why

exa 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 9d 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.

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.
