index · Smart Code Search MCP Server MCP: Risk & Policy

WHAT IT DOES

What index does on Smart Code Search MCP Server

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

WHY IT NEEDS A POLICY

Why index needs a policy

Indexing a project involves reading source files and writing embedding/index data to storage. This is a Write operation as it creates new data (the search index) that can presumably be rebuilt or updated. It has no destructive or financial implications, but misuse could cause performance issues or index corruption.

From the tool's definition 'Index a project for semantic search' — creates/writes search index data for the project

Verdict

index Rate-limited

index 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.

FAQ

Questions about index

What does the index tool do? +

Index a project for semantic search. It is categorised as a Write tool in the Smart Code Search MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on index? +

Register the Smart Code Search MCP Server MCP server in PolicyLayer and add a rule for index: 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 Smart Code Search MCP Server. Nothing to install.

What risk level is index? +

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

Can I rate-limit index? +

Yes. Add a rate_limit block to the index 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 index completely? +

Set action: deny in the PolicyLayer policy for index. 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 index? +

index is provided by the Smart Code Search MCP Server MCP server (stevenjjobson/scs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
