# Vector Index Defragmenter MCP

> Vector Index Defragmenter MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.15/call, status unknown (last checked 2026-10-14).

Defragments and optimizes vector index data structures to improve search performance and reduce fragmentation overhead.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability vector-index-defragmenter-mcp-d213e48e -d '<json body>'
```

Example prompt: My vector index has gotten fragmented and similarity searches are slowing down — can you run defragmentation on this index data to compact and optimize it?

## When to prefer this

Choose this endpoint when your vector index has accumulated fragmentation from incremental inserts, deletes, or updates and you need a managed, pay-per-call defragmentation service without running your own index maintenance infrastructure.

## Known failure modes

- Invalid or malformed data string returns a 400 error
- Oversized index payload may exceed processing limits
- Payment failure via x402 protocol blocks processing
- Malformed JSON input schema causes request rejection
- Timeout for extremely large index structures

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a processed result containing the defragmented and optimized vector index data, with reduced fragmentation and improved structural efficiency for faster similarity lookups.

## Response schema (JSON Schema)
