AI agents use code_graph_ingest_repo to create or update resources in Code Graph Knowledge System — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Code Graph Knowledge System environment.
Based on the tool name and server context (transforming code repositories into a Neo4j knowledge graph), this tool likely reads a repository and writes/creates nodes and relationships in the graph. This is a Write operation. However, the empty description reduces confidence significantly.
From the tool's definition Tool name 'code_graph_ingest_repo' and server context suggest ingesting a repository into the knowledge graph. Description is empty, lowering confidence.
Documented attack patterns abuse exactly the kind of access code_graph_ingest_repo gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Code Graph Knowledge System, and nothing reaches the server without passing your rules. This is the rule we recommend for code_graph_ingest_repo:
{
"version": "1",
"default": "deny",
"tools": {
"code_graph_ingest_repo": {
"limits": [
{
"counter": "code_graph_ingest_repo_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}code_graph_ingest_repo 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.

code_graph_ingest_repo. It is categorised as a Write tool in the Code Graph Knowledge System MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Code Graph Knowledge System MCP server in PolicyLayer and add a rule for code_graph_ingest_repo: 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 Graph Knowledge System. Nothing to install.
code_graph_ingest_repo 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 code_graph_ingest_repo 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 code_graph_ingest_repo. 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.
code_graph_ingest_repo is provided by the Code Graph Knowledge System MCP server (royisme/codebase-rag). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Code Graph Knowledge System, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
