Manually trigger a full reindex of the codebase. This will scan all files and update the embeddings cache. Useful after large code changes or if the index seems out of date.
AI agents use b_index_codebase to create or update resources in Smart Coding MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Smart Coding MCP environment.
This tool scans files and writes/updates an embeddings cache. It creates or overwrites cached index data, which is a reversible write operation. It does not delete source files or execute user code, but it does modify stored index state. Misuse could cause excessive resource consumption or stale cache issues, hence medium severity.
From the tool's definition 'Manually trigger a full reindex of the codebase. This will scan all files and update the embeddings cache.'
Risk signalsBulk/mass operation — affects multiple targets
Documented attack patterns abuse exactly the kind of access b_index_codebase gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Smart Coding MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for b_index_codebase:
{
"version": "1",
"default": "deny",
"tools": {
"b_index_codebase": {
"limits": [
{
"counter": "b_index_codebase_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}b_index_codebase 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.

Manually trigger a full reindex of the codebase. This will scan all files and update the embeddings cache. Useful after large code changes or if the index seems out of date. It is categorised as a Write tool in the Smart Coding MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Smart Coding MCP server in PolicyLayer and add a rule for b_index_codebase: 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 Coding MCP. Nothing to install.
b_index_codebase 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 b_index_codebase 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 b_index_codebase. 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.
b_index_codebase is provided by the Smart Coding MCP server (omar-haris/smart-coding-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
