What the server does

Coding agents are good at reading code, but they struggle with whole-program questions:

Does user-controlled input actually reach this SQL call, or does sanitization cut the flow off?
Who really invokes this function across the codebase?
What is the complete evidence chain from source to sink?

Credentials and setup notes

JDK 21 The build pulls CPG artifacts from Maven Central and Sonatype Central Snapshots (the latter for main-SNAPSHOT until CPG 11.x lands as a stable release on Central). No sibling checkouts required.

More MCP options

Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
