What re_capa does on Rekit
AI agents call re_capa as a supporting operation in Rekit workflows.
Why re_capa is rated Low
Without any rule in front of it, every call an agent makes to re_capa happens silently: no trail, no cap, no way to know it misbehaved until something breaks downstream.
Attacks that exploit this kind of access
The rule that runs re_capa safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Rekit, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For re_capa, this is the rule to start with:
re_capa gets a rate cap, and everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Rekit, apply this rule, and every re_capa call is checked against it from then on.
Questions about re_capa
Capability detection + MITRE ATT&CK technique mapping (capa; PE and ELF). It is categorised as a Other tool in the Rekit MCP Server, which means it performs auxiliary operations.
Register the Rekit MCP server in PolicyLayer and add a rule for re_capa: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Rekit. Nothing to install.
re_capa is a Other tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the re_capa rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for re_capa. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
re_capa is provided by the Rekit MCP server (Amz34/rekit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
