Comparison

E2B vs io.github.ChiR24/unreal-engine-mcp

E2B is an MCP server published by e2b-dev. Marketplaces we read that list it: 1 (Docker MCP Catalog). io.github.ChiR24/unreal-engine-mcp is an MCP server published by ChiR24. Marketplaces we read that list it: 2 (Official MCP Registry, Docker MCP Catalog). As of our marketplace pass on 2026-10-18. This pair was picked by a reader, not by our comparison rule, so search engines are asked not to index the page.

Each figure is the marketplace's own and is never added up across marketplaces. A marketplace that publishes no figure shows none: no number is not zero.

Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.

What each says it does

E2B

How to run each

E2B As a local MCP server: Docker image

Claude Code

claude mcp add --env "E2B_API_KEY=<YOUR_E2B_API_KEY>" --transport stdio e2b -- docker run -i --rm -e E2B_API_KEY mcp/e2b

Requires: E2B_API_KEY (secret)

io.github.ChiR24/unreal-engine-mcp As a local MCP server: npm package

Claude Code

claude mcp add --env "MCP_AUTOMATION_CAPABILITY_TOKEN=<YOUR_MCP_AUTOMATION_CAPABILITY_TOKEN>" --env "UE_PROJECT_PATH=<YOUR_UE_PROJECT_PATH>" --transport stdio unreal-engine-mcp -- npx -y unreal-engine-mcp-server

Requires: MCP_AUTOMATION_CAPABILITY_TOKEN (secret), UE_PROJECT_PATH
