AI agents call tokrepo_verify to retrieve information from TokRepo — AI Asset Registry without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool is explicitly described as 'read-only' and its outputs (hashes, trust scores, evidence, warnings, schemas) are informational and verification-focused. It performs no modifications, deletions, executions, or financial operations. It sits in the security gate before installation (tokrepo_codex_install), confirming it is a pre-action inspection tool that retrieves and analyzes asset metadata only.
From the tool's definition Read-only asset trust verification. Produces content hash, install plan hash, policy decision, permission envelope, trust_score_v2, evidence_bundle, SBOM-lite, signature_evidence, blockers, warnings, schemas, and safe next actions.

STEP 2 of ATOMIC ACTION 2 (install safely into this repo). Read-only asset trust verification. Produces content hash, install plan hash, policy decision, permission envelope, trust_score_v2, evidence_bundle, SBOM-lite, signature_evidence, blockers, warnings, schemas, and safe next actions before activation. Call AFTER tokrepo_install_plan, BEFORE tokrepo_codex_install. It is categorised as a Read tool in the TokRepo — AI Asset Registry MCP Server, which means it retrieves data without modifying state.
Register the TokRepo — AI Asset Registry MCP server in PolicyLayer and add a rule for tokrepo_verify: 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 TokRepo — AI Asset Registry. Nothing to install.
tokrepo_verify 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 tokrepo_verify 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 tokrepo_verify. 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.
tokrepo_verify is provided by the TokRepo — AI Asset Registry MCP server (tokrepo-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
