HF Hub MCP Server API Activity (from Jun 2025)

What's going on??

+
+
+

Initialize Requests?

+
    +
  • +

    1% MCP Traffic -> Tool Call

    +
    • +
  • +

    Unreliable proxy for MCP install

    +
    • +
+

Tool Calls: More != Better

+
    +
  • +

    Human vs. Agent usage... high call rate may indicate failure.

    +
    • +
+

Sessions with > 1 Tool Call

+
    +
  • +

    2% Conversion rate from Initialize

Change 1: Stateless Protocol

+
+
+
github.com/evalstate
+
Current Protocol - Stateful Connection
+ +
+
+
github.com/evalstate
+
Future Protocol - No Initialize, Capabilities with Request/Response Pair
+ +
+
+
github.com/evalstate
+ +

Change 2: - MRTR (Multi Round Trip Requests)

+
+
+
github.com/evalstate
+
Sampling and Elicitation
+ +
+
+
github.com/evalstate
+
Multi-round trip flow + stateful request
+
+
+ +
+
+ +
+
+
+
+
github.com/evalstate
+
Chat interaction vs API payload
+
+
+ +
+
+ +
+
+
+
+
github.com/evalstate
+
MRTR flow + Cumulative Request
+
+
+ +
+

Change 3: Real Sessions (Cookies)

+
+
+
github.com/evalstate
+
MCP cookies for session semantics

Initialize Events might tell us whether someone has the MCP Server installed

Raw Tool Calls is a potentially misleading vanity metric

Sessions that convert to at least one tool call

typical ratio is 1.77% of initialize events are "interesting"

## Robust Agent Loops of hundreds of turns + +## Adoption of MCP Apps at Internet Scale + +## Create, control and manage Resources

discoverable with a "discovery" endpoint
