v3.1.0 M4: Return the affordance keys (task_types) applicable
AI agents call spatial_affordances 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.
This tool retrieves or queries available affordance keys and task types from the knowledge base. It performs a pure read operation without modifying, executing, or deleting any data. The return of metadata about available options is characteristic of a Read category tool, presenting minimal risk even if misused by an agent.
From the tool's definition Tool name 'spatial_affordances' and description 'Return the affordance keys (task_types) applicable' indicate a query/retrieval operation that returns metadata about available task types.
Documented attack patterns abuse exactly the kind of access spatial_affordances 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_affordances:
{
"version": "1",
"default": "deny",
"tools": {
"spatial_affordances": {}
}
}spatial_affordances 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 affordance keys (task_types) applicable. 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_affordances: 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_affordances 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_affordances 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_affordances. 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_affordances 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.
