AI agents use update-codebase-insight to create or update resources in CodeAnalysis MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CodeAnalysis MCP Server environment.
The verb 'update' combined with 'codebase-insight' indicates this tool modifies stored analysis or metadata about the codebase. While we cannot confirm the exact scope without documentation, update operations on codebase-related systems typically fall under Write (reversible modification). Severity is high because updates to codebase insights could affect downstream analysis or development decisions.
From the tool's definition Tool name 'update-codebase-insight' contains 'update', indicating modification of data. Description is empty, limiting certainty. The tool name suggests writing to codebase insights or analysis state.
Documented attack patterns abuse exactly the kind of access update-codebase-insight gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and CodeAnalysis MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for update-codebase-insight:
{
"version": "1",
"default": "deny",
"tools": {
"update-codebase-insight": {
"limits": [
{
"counter": "update-codebase-insight_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update-codebase-insight 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.
Free to start. No card required.
update-codebase-insight. It is categorised as a Write tool in the CodeAnalysis MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the CodeAnalysis MCP Server MCP server in PolicyLayer and add a rule for update-codebase-insight: 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 CodeAnalysis MCP Server. Nothing to install.
update-codebase-insight is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update-codebase-insight 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 update-codebase-insight. 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.
update-codebase-insight is provided by the CodeAnalysis MCP Server MCP server (0xjcf/mcp_codeanalysis). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from CodeAnalysis MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
