Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

bandwidth
bandwidth_cost_calc
Calculate cloud API egress bandwidth costs for a given payload size and monthly traffic. Returns cost at 25%, 50%, and 75% reduction scenarios.
compare
compare_payloads
Compare an original payload to an optimized version. Returns size reduction %, removed field paths, and depth change.
field
field_prune_suggest
Identify and suggest unnecessary fields for removal from a JSON payload. Flags debug/temp/internal/deprecated fields, null values, empty arrays, and _ prefix fields.
payload
payload_analyze
Analyze a JSON API response payload structure — field count, size in bytes, max nesting depth, type distribution, null field count, and redundancy signals (empty arrays, null values).

API Payload Auditor — questions

Answers built from our own checks of this server.

What can API Payload Auditor do?
It exposes 4 tools, read directly from the server on our last check. Among them: bandwidth_cost_calc, compare_payloads, field_prune_suggest, payload_analyze. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is API Payload Auditor working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 161 ms. The bar chart above shows every period we have measured.
How do I connect API Payload Auditor?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does API Payload Auditor need an API key?
No. API Payload Auditor completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is API Payload Auditor?
It answers our handshake in 161 ms on average, which is faster than 71% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is API Payload Auditor open source?
Yes — 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
