Fetch the AgentForge Trust Score for an MCP server. Returns the overall score (0-100), per-dimension breakdown (code_health, security_scan, behavioral_audit, community_trust, eu_compliance), and badges. Use before connecting to any MCP server.
AI agents call check_trust to retrieve information from Agentforge Trust without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
check_trust retrieves pre-computed trust metrics and audit data from the AgentForge system without side effects. It enables informed decision-making before connecting to servers but does not itself execute code, modify data, delete records, or move funds.
From the tool's definition Tool description states it 'Fetch[es] the AgentForge Trust Score' and 'Returns' data—purely retrieval operations with no modification, deletion, or execution of external code.

Fetch the AgentForge Trust Score for an MCP server. Returns the overall score (0-100), per-dimension breakdown (code_health, security_scan, behavioral_audit, community_trust, eu_compliance), and badges. Use before connecting to any MCP server. It is categorised as a Read tool in the Agentforge Trust MCP Server, which means it retrieves data without modifying state.
Register the Agentforge Trust MCP server in PolicyLayer and add a rule for check_trust: 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 Agentforge Trust. Nothing to install.
check_trust 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 check_trust 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 check_trust. 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.
check_trust is provided by the Agentforge Trust MCP server (kovy/agentforge-trust-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Every MCP server has a record like this.
