MCP Builder

Decodes a JWT without trusting it and lints the header and claims: alg none, remote jku/x5u keys, missing or expired exp, nbf/iat clock skew, millisecond timestamps, long lifetimes, iss/aud mismatches, sensitive data in the payload, and HMAC signature checks with a secret from an env var. Use when a login or API call fails with 401, or when reviewing token settings. Includes a stdlib Python inspector with --self-test. 来源：https://prompts.chat/prompts/cmvexfiys000njr08n2k8i3bq

Checks retry, backoff and timeout settings across a call chain to prevent retry storms. Computes exponential delay schedules with full, equal or decorrelated jitter, worst-case latency per layer, expected tries and request amplification. Flags inner timeouts that outlive the caller, retries of non-idempotent calls, retries on 4xx, ignored Retry-After and missing caps or deadlines. Includes a stdlib Python calculator with --self-test. 来源：https://prompts.chat/prompts/cmvhs9wa30003ig07nir0b8wf

Compares an OpenAPI YAML/JSON spec to a list of implemented routes and flags drift: missing operations, extra routes, method mismatches, and path-parameter shape differences. Use when reviewing API PRs, before a release, or asking "does our code still match the OpenAPI?". Includes a stdlib Python checker with --self-test. 来源：https://prompts.chat/prompts/cmvan841x0005l206qhg2xrll

Simulates API rate limits before you ship them - token bucket, fixed window, sliding log and sliding counter, per client, endpoint, tier or global - against generated or recorded traffic with retrying clients. Shows who gets 429s and for how long, fixed-window boundary bursts, retry herds, noisy neighbours, abusive clients that still get through and peaks over backend capacity. Includes an offline stdlib Python simulator with --self-test. 来源：https://prompts.chat/prompts/cmvyxuu2b0007l907kap4o8qp
