Versions
This tool's calls by the server version that answered them
| Version | First seenWhen mcpspan first saw a call answered by this version, in the data still kept. | Calls | ErrorsThe share of calls that failed: an error the tool reported, an exception it threw, or arguments the server refused. Calls to names the server does not have are counted apart. | MedianHow long calls took: half of them were faster than the median. p95 under it: 95 in 100 were faster, so it shows the slow tail the median hides. |

Repeated calls
Same arguments as the call before, in the same session
6 of 48 calls (13%)
An agent sending the same call again usually did not get what it needed from the answer: an error it could not act on, or a result it did not recognise as complete. Sessions show where it happened.
Right before it went wrong
Before 8 repeated or failed calls, in their sessions
What the agent called just before get_flight_status repeated itself or failed. One call standing out usually did not do what the agent expected: a click that did not land, a search that came back empty.

3 calls refused before the tool ran

The argument agents get wrong most is usually one whose description leaves room for the wrong shape.
Parameters agents send
Names and types only
A name the schema does not have, or one that arrives as more than one type, is usually a description the agent is misreading.
