v3.1.0 M4: Return the neighborhood id + members for a file.
AI agents call spatial_neighborhood to retrieve information from Codevira MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool queries and retrieves structural metadata (neighborhood ID and member information) about a code file. It performs a read-only lookup operation with no capability to modify, delete, or execute code. The return of identifiers and membership lists is informational only. Low severity because misuse would at worst expose organizational code structure without enabling further damage.
From the tool's definition Tool description states 'Return the neighborhood id + members for a file' — a retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access spatial_neighborhood gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Codevira MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for spatial_neighborhood:
{
"version": "1",
"default": "deny",
"tools": {
"spatial_neighborhood": {}
}
}spatial_neighborhood is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

v3.1.0 M4: Return the neighborhood id + members for a file. It is categorised as a Read tool in the Codevira MCP MCP Server, which means it retrieves data without modifying state.
Register the Codevira MCP server in PolicyLayer and add a rule for spatial_neighborhood: 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 Codevira MCP. Nothing to install.
spatial_neighborhood is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the spatial_neighborhood 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 spatial_neighborhood. 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.
spatial_neighborhood is provided by the Codevira MCP server (sachinshelke/codevira). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Codevira MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
