runjs
The only MCP server you need: let your LLM generate and safely execute JavaScript -- including fetch API calls, JSONPath ETL, built-in resiliencey, and secrets management
Install
$ npx -y runjsInstalling via npx/uvx/npm install executes arbitrary code from the public registry on your machine. This is the install-risk semantic of the MarketNow catalog — verify the publisher before running it.
How MarketNow scored this
Sentinel Index Heuristics — a security-first estimate from public signals:
- Package age and release activity (stale repositories lose points)
- Verified adoption: registry downloads or GitHub stars, not follower counts
- Typosquat distance against the 150 most-installed MCP packages
- Injection markers scanned in the package description
Heuristic, not a guarantee. For verified agent credentials and revocation, see the MarketNow Trust API.
What is runjs?
The only MCP server you need: let your LLM generate and safely execute JavaScript -- including fetch API calls, JSONPath ETL, built-in resiliencey, and secrets management Indexed by MarketNow with trust 63/100 (Runs registry code).
How do I install it?
Run $ npx -y runjs Installing via npx/uvx/npm install executes arbitrary code from the public registry on your machine. This is the install-risk semantic of the MarketNow catalog — verify the publisher before running it.
What does the trust score mean?
Security-first heuristic over public signals (age, adoption, typosquat distance, injection markers). It is not a popularity ranking and not a guarantee of safety. runjs scores 63/100.
