TL;DR: MCP servers can see request volume and latency, but not reliably distinguish Claude Code, Cursor, cloud-hosted agents, or spoofed clients from one another, according to Fingerprint. That visibility gap turns MCP analytics into an identity problem, not a dashboard problem, because user agent strings and HTTP metadata alone do not establish trustworthy caller identity.
Editorial analysis by NHI Mgmt Group, based on content published by Fingerprint: “How to detect which AI tools call your MCP server”.
Key questions
Q: How should teams handle MCP traffic when caller identity is not trustworthy?
A: Treat the traffic as observable but not yet attributable.
Q: Why do user-agent strings fail as a governance signal for MCP traffic?
A: Because they are self-reported, often generic, and easy to imitate.
Q: What are the signs that MCP analytics are missing an identity layer?
A: The clearest sign is when traffic dashboards can show volume but cannot reliably separate developer sessions, hosted agents, and impersonating clients.
Practitioner guidance
- Instrument caller identity before trusting MCP metrics Add an identity verification layer to MCP telemetry so request counts are annotated with caller confidence, claimed tool, and origin context before they feed reporting or routing decisions.
- Separate local and hosted AI usage in reporting Track datacenter and ASN signals alongside tool names so developer workstation traffic does not get merged with cloud-hosted agent traffic in capacity or adoption reports.
- Treat spoofed callers as a distinct governance case Flag requests whose claimed identity fails verification and route them to a different review path from merely unknown or uncategorised callers.
Bottom line: MCP analytics that rely on request volume and User-Agent strings leave teams with activity data but not trustworthy caller identity.

Identity visibility is the missing control plane for MCP. An MCP server that can count requests but not verify callers is operating with incomplete governance data. The identity signal is what converts traffic into something you can safely prioritise, trust, and audit. For practitioners, that means analytics and access governance have to share the same identity layer, or reporting will keep overclaiming certainty.
A few things that frame the scale:
- 24,008 unique secrets were exposed in MCP configuration files in 2025 alone, the protocol's first year of widespread adoption, according to the State of Secrets Sprawl 2026.
A question worth separating out:
Q: What should teams do when an MCP caller claims to be a known tool but fails verification?
A: Treat that as a spoofing event, not a neutral analytics record. Separate it from verified traffic, preserve the original request metadata, and avoid using the claimed tool name in planning or access decisions until the identity can be established through stronger proof.
