SchemaSure — structured extraction

io.github.noamjose/schemasurev0.3.0Image, Video & Audio

Source repository no longer publicly accessible (HTTP 404). This may be deliberate: repositories are sometimes made private or relocated. Evidence.

Extract schema-valid JSON from text/HTML or document images. Pay per call via x402 V2.

The current version, v0.3.0, was published to the official MCP registry on 2026-07-31. It is distributed as @noamjose/schemasure on npm, filed under Image, Video & Audio by this index, and declares 4 environment variables. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; the index's current counts put this record in context.

In-path gate · all MCP tools

Using SchemaSure — structured extraction in Claude, Cursor, Gemini CLI, Cline, or Zed?

MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself (use Install this server for that).

Install the mcpindex gate (one command)

Rewrites your MCP host config so each server launches behind the gate. Inspect first: curl -fsSL https://mcpindex.ai/install.sh | less

Limits of this verdict

- Semantic screen only - the deterministic conformance probe has not run on this server
- Confidence is reported but not yet calibrated (v1)
- Screen reads the tool description, not the live behavior
- advisory
- registry description only no input schema
- screen model 8b
- Still current: the description we screened is unchanged, re-checked against the registry

Semantic screen: an LLM judge reads the tool description for hidden instructions (status PARTIAL). A pass means the description is not lying, not that the tool is safe: a high-capability tool with an honest description still warrants caution. The deterministic conformance probe has not been run on this server yet, so the screen here is semantic-only. Posture: advisory. Confidences are reported but not yet calibrated (calibrated=false at v1). Full verdict history is not shown on this page.

That verdict was true at screening time (snapshot 2026-09-02).

Contracts can change after screening, with no version bump. The gate pins SchemaSure — structured extraction’s tool contracts on first sight and holds any silent change before your agent acts - the check that keeps being true on Tuesday.

Cite this record

People vet a server before wiring it in. One line on your project site or docs answers that with an independent record: screening verdict, registry provenance, contract drift history. It stays current as new screens and drift events land.

Environment variables

SCHEMASURE_API_URL

Base URL of SchemaSure. Text has free V1 evaluation without a wallet; image extraction is V2-only and always requires a wallet.

SCHEMASURE_TIMEOUT_MS

Per-call request timeout in milliseconds.

SCHEMASURE_PRIVATE_KEY

secret

Optional 0x-prefixed EVM key. Enables paid x402 V2 text and image calls; signs Base USDC payments locally. Never sent to SchemaSure.

SCHEMASURE_MAX_PRICE_USD

Client-side spend cap in USD per call (paid mode). The client refuses to pay more than this, even if the server advertises a higher price.

Provenance

Each verdict is bound to a hash of the exact description it judged, so a re-crawl that changes the text produces a new record rather than silently inheriting this one. Verdict history is hash-chained and anchored to Bitcoin via OpenTimestamps (latest confirmed at block 964,988). Verify it yourself.
