MCP Server Trust Scoring

AIM applies a sophisticated 8-factor weighted algorithm to calculate trust scores for MCP servers, enabling intelligent security decisions about which servers your agents can connect to.

How MCP Trust Scoring Works

Every MCP server registered with AIM receives a trust score from 0-100 based on 8 weighted factors. This score determines whether agents can connect to the server and what level of monitoring is applied.

Trust Score Progression

Registered:~50% (pending verification)

1st Attestation:~60% (+attestation consensus)

3+ Attestations:~75% (consensus threshold met)

30+ Days:~85% (+age & history bonus)

Fully Trusted:90%+ (all factors optimized)

Trust Score Ranges

90%

Excellent

80-100: Trusted

Agents can connect freely, minimal monitoring

70%

Good

60-79: Acceptable

Agents can connect with standard monitoring

50%

Fair

40-59: Caution

Connection requires policy approval, increased monitoring

30%

Poor

0-39: Untrusted

Connections blocked by default, admin approval required

MCP vs Agent Trust Scoring

MCP trust scoring uses the same 8-factor approach as agent trust scoring, but with different factor implementations:

Agent Trust Factors

• Verification Status (Ed25519)
• Uptime & Availability
• Action Success Rate
• Security Alerts

MCP Trust Factors

• Attestation Consensus
• Connection Health
• Capability Stability
• Security Posture
