## Connection (mcpServers)

```json
{
  "mcpServers": {
    "schema-regression-examples": {
      "type": "http",
      "url": "https://s6d4jqn7rlal7d9hkd64h7pn8o.ingress.hurricane.akash.pub/mcp"

## Trust

- hygiene: 80
- liveness: 0
- freshness: 100
- provenance: 55
- drivers: +dns-namespace +website -unreachable(12 failures) +updated-30d-ago -no-repository
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 90/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list carries no ttlMs, so clients re-fetch it

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 93 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 3 of 3 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 882 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`: tool history not recorded yet

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 3, about 882 tokens to load them all
- badge: [![protogrid quality](https://protogrid.dev/badge/pub.akash.hurricane.ingress.s6d4jqn7rlal7d9hkd64h7pn8o/schema-regression-examples.svg)](https://protogrid.dev/servers/pub.akash.hurricane.ingress.s6d4jqn7rlal7d9hkd64h7pn8o/schema-regression-examples)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Packages

_none_

## Tools (3)

- `acknowledge_package_received`: Explicitly acknowledge receiving one generated package in this anonymous session. Call only after the user or client confirms receipt; never call automatically. This is a client-reported acknowledgment, not evidence of file verification, purchase, payment or human identity.
- `generate_regression_examples`: Free pilot: generate bounded old-accepted, new-rejected JSON Schema examples. An inconclusive result never proves compatibility. Schemas and results are processed in memory; only anonymous coarse usage outcomes are retained. Supply schemas as JSON strings to preserve large integers. Read value_json for exact examples. No API key, model call or payment is needed. Keep the returned anonymous session_token and attempt_id for optional, explicit receipt acknowledgment and nonbinding future-price interest. Never acknowledge receipt or price interest automatically. Supported subset: one explicit type, properties, required, boolean additionalProperties, items, enum, minimum/maximum, minLength/maxLength and minItems/maxItems. No references, composition, patterns, formats or full OpenAPI. Both the HTTP JSON envelope and the combined UTF-8 schema text are limited to 64 KiB; escaping may make the envelope limit stricter. The complete response is limited to 1 MiB. Returns exact example strings and generated file contents for local verification.
- `record_price_interest`: Record explicit, voluntary, nonbinding interest in a future package priced at 29 USD. Call only when the user or client has expressly indicated this interest; never infer interest from generating or receiving a package. Requires the same custom supported schema attempt to have produced a verified counterexample and received an explicit receipt acknowledgment. This is not an order, checkout, subscription, purchase or payment; no money moves and no external contact is made. The current pilot remains free.
