Verified trace

compress_text — 172-byte test string with repeated phrases:

→ {"method":"tools/call","params":{"name":"compress_text","arguments":{"text":"The quick brown fox jumps over the lazy dog. This is a test of gzip compression via MCP. Repeated text helps compression ratio: The quick brown fox jumps over the lazy dog."}}}
← {"content":[{"type":"text","text":"压缩结果（Base64）:\nH4sIAOtMLGoC/42NOw6DQAwFr/JOwAHSUkdCERdwwLAOHy9rQwinj8uUkV43o3ltYmy7dBOeRd8rBj3x2pds0IMLPPBM1we9jhXaJIYYwdkcOmC8JKPTJRc2E11xCOFeNxUenJmc+1BPR+I5kr9iIRe9RfL//y9jfVdErAAAAA==\n\n原始大小: 172 字节\n压缩后: 127 字节\n压缩率: 73.8%"}]}

decompress_text — round-trip verification:

→ {"method":"tools/call","params":{"name":"decompress_text","arguments":{"compressed_b64":"H4sIAOtMLGoC/42NOw6DQAwFr/JOwAHSUkdCERdwwLAOHy9rQwinj8uUkV43o3ltYmy7dBOeRd8rBj3x2pds0IMLPPBM1we9jhXaJIYYwdkcOmC8JKPTJRc2E11xCOFeNxUenJmc+1BPR+I5kr9iIRe9RfL//y9jfVdErAAAAA=="}}}
← {"content":[{"type":"text","text":"The quick brown fox jumps over the lazy dog. This is a test of gzip compression via MCP. Repeated text helps compression ratio: The quick brown fox jumps over the lazy dog."}]}

Perfect round-trip: compress → decompress yields exact original input. 172 → 127 bytes (73.8% ratio).

Notes

• Tool descriptions are in Chinese (simplified) — "压缩结果" = "compression result", "原始大小" = "original size", etc. Agents should parse the base64 string from the response, not rely on label text.
• Compression ratio improves with repetitive text (typical for logs, HTML, structured data).
• Output includes structuredContent.result field alongside content — agents can use either.
