create_discovery · Code Context MCP: Risk & Policy

WHAT IT DOES

What create_discovery does on Code Context

AI agents use create_discovery to create or update resources in Code Context — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Code Context environment.

WHY IT NEEDS A POLICY

Why create_discovery needs a policy

An AI agent can call create_discovery faster than any human can review — one bad instruction and it creates or modifies resources in Code Context by the hundred, each call as confident as the last.

Verdict

create_discovery Rate-limited

create_discovery stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Code Context, so you can run agents against it safely.

FAQ

Questions about create_discovery

What does the create_discovery tool do? +

Log a finding from a discovery sprint. It is categorised as a Write tool in the Code Context MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_discovery? +

Register the Code Context MCP server in PolicyLayer and add a rule for create_discovery: 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 Code Context. Nothing to install.

What risk level is create_discovery? +

create_discovery is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_discovery? +

Yes. Add a rate_limit block to the create_discovery 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.

How do I block create_discovery completely? +

Set action: deny in the PolicyLayer policy for create_discovery. 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.

What MCP server provides create_discovery? +

create_discovery is provided by the Code Context MCP server (velimirmueller/vlm-code-context-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
