e2b

e2b is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from agentalabs/agenta-plugin. Its token cost is not measured, scanned A, original, MIT.

An MCP server is a service that lets a coding agent use an external capability. This one provides cloud sandboxes where TypeScript and Python code can run separately from the main project.

In plain words
What is it for?
Use it to run TypeScript or Python in an E2B cloud sandbox through the Model Context Protocol. The input only documents its setup and does not specify further workflows.
Why use it?
It can provide an isolated place to execute code when the local project environment is unsuitable or needs separation. It requires an E2B API key to connect.

Written for no agent in particular: it speaks MCP, so any client can run it. Also seen: listed in a Claude config.

One of 10 entries in .mcp.json upstream. Installing this one merges just its entry into your config; the other 9 are separate, each on its own page.

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.

Security

Grade A, and why

e2b 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 2mo 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.
