How this service works
Repairs truncated or malformed LLM JSON outputs (trailing commas, markdown fences, single quotes) so multi-agent pipelines never crash. (Live x402 v2, IETF MPP & MCP endpoint at https://mcp-compiler.agentdiet.dev/v1/schema-repair)
Output
A repaired, valid JSON object where all malformations (trailing commas, markdown fences, single quotes, truncation) have been deterministically corrected, ready for immediate use in downstream pipeline steps.
Example use cases
Fixing LLM output in multi-agent pipeline
“My agent just returned this malformed JSON with trailing commas and it's crashing the next step in my pipeline — can you repair it? Here's the raw string: {"model": "gpt-4", "tokens": 1500,}”
Stripping markdown fences from AI response
“The LLM wrapped its JSON in triple backticks and now my parser is failing — can you clean up this raw output and give me proper JSON? The string is: ```json
{"status": "ok", "score": 0.95}
```”
Recovering single-quoted JSON from agent output
“I got this JSON with single quotes instead of double quotes from an AI agent and it won't parse — can you fix it to valid JSON? Here it is: {'user': 'bob', 'active': true}”
Technical details
Endpoint
GEThttps://mcp-compiler.agentdiet.dev/v1/schema-repair?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent or LLM pipeline produces structurally malformed JSON (trailing commas, markdown fences, single quotes, truncation) and you need a deterministic, rule-based fix rather than an LLM re-generation. Ideal for multi-agent orchestration layers where reliability and low latency matter more than probabilistic correction.
Side effects
- JSON is too severely truncated or corrupted to deterministically repair — returns error or best-effort partial result
- Input string is not JSON at all (e.g. plain text, binary) — may return parse error
- Edge cases with deeply nested or extremely large JSON strings may hit query parameter length limits
- Network or service unavailability returns HTTP 5xx
