ephemora-cell-mcp is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from MichaelS1011/ephemora-cell. Its token cost is not measured, scanned A, original, no licence file.

A local execution service for running AI-generated code as WebAssembly, a portable code format, with explicit limits on CPU, memory, time, network or other input/output, and files.

In plain words

What is it for?: Use it to execute generated code locally with defined resource and access boundaries.
Why use it?: It limits what untrusted generated code can use on the host system. This reduces the risk of runaway computation or unwanted access to files and other resources.

Security

Grade A, and why

ephemora-cell-mcp 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 1mo 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
