Exa MCP Server connects AI agents to Exa, a service for searching the web, fetching webpage content, and carrying out multi-step research. MCP, or Model Context Protocol, lets compatible AI clients call these capabilities as tools. The catalogue skills, MCP server, and plugin provide ways for coding agents to use Exa for web research.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

exa-mcp-server 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 it actually says
{
"name": "exa-mcp-server",
"version": "3.4.2",
"description": "Official Exa MCP for web search, content fetching, and multi-step research.",
"mcpServers": {
"exa": {
"httpUrl": "https://mcp.exa.ai/mcp"
}
}
}
What ships with it
1 file beside gemini-extension.json in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

exa-mcp-server is a plugin published in the GitHub repository exa-labs/exa-mcp-server (5,135 stars, last pushed 8d ago), licensed MIT. Its token cost is not measured: this kind of file is read by the harness, not the model. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-23.
