Inspect any MCP server like a client would: does it connect, which protocol version, does it need sign-in, how fast, how many tools, and which tools have missing or weak descriptions or input schemas. A checklist of fixes for server owners.
Agent-readiness audit of a website: can AI agents and assistants find and use it? Checks llms.txt, agent card, MCP endpoint, OpenAPI, pay-per-call manifest, sitemap, and robots.txt rules for AI crawlers. Score, what was found, and fixes.
Repair broken JSON (typical of model output) into valid JSON: removes code fences, comments and stray text, fixes single quotes, unquoted keys, trailing commas, Python literals (True/None) and trunca…
Review a code snippet: bugs, security issues, performance and readability problems, each with severity, the line it concerns and a concrete fix, plus an overall verdict.
Full agent-readiness report for a website or API: everything in the readiness audit plus a quality review of the agent card, OpenAPI document, llms.txt, MCP server (connects, tools, descriptions) and pay-per-call manifest (does a listed endpoint really answer 402), CORS for in-browser agents, and an AI-written prioritised fix plan.
Diagnose a public x402 origin with 25 linter and 14 compliance checks, plus six separate request-example/schema and challenge consistency diagnostics. Use quote_mode fast for an immediate 402, resend…
Compare exact prices across eight models: GPT-6 Luna, GPT-6.1 Sol, Ministral 3B/8B/14B, Nemotron 3 Nano and Qwen3 Next/Coder Next. Review a recommendation and supported model/effort alternatives, the…
Use when an agent wants to test a third-party endpoint for a 402 challenge, latency and response shape without paying it. Returns One bounded x402 endpoint request and payment-flow evaluation. $0.01.
Use when an agent needs run python. Returns Runs a short Python program in an isolated sandbox and returns its output: exit code, stdout/stderr (64 KB each), duration, up to 3 artifact files in ./out…
Generates an llms.txt file for a website from caller-supplied sitemap entries and page titles, spec-compliant with llmstxt.org: one H1, a blockquote summary, H2 sections with link lists and an option…
Checks a web page for accessibility (a11y) problems from caller-supplied HTML: document language, title, image alt text, form labels, heading order, zoom, landmarks, link text, table headers, iframes…

Repairs broken JSON: markdown fences, comments, trailing commas, single quotes, unquoted keys, Python literals (True, False, None) and truncated endings. Pure code first; the model is asked once only…
Validates JSON data against a JSON Schema (draft 2020-12): valid true or false, and up to 50 errors with the instance path, the keyword and the message. Schema and data are each limited to 200 KB. Re…
Explains a code snippet (max 20,000 characters): detected language, a summary, a step-by-step explanation, the functions and classes it defines, and possible bugs and security issues with line number…
A regular expression from a description, with examples that must match and examples that must not. The pattern is returned only when every example passes when tested in the service (one retry with th…
SQL from a question and a schema (CREATE TABLE statements or a JSON description of tables and columns), for postgres (default), mysql, sqlite or bigquery. The tables and columns used are checked agai…
Split a long text into chunks for retrieval (RAG): split on paragraphs, then sentences, then words, each chunk within maxTokens (default 500) with the overlap you ask for (default 50 tokens). Each ch…
Check Python for syntax errors, lint and type mistakes, unsafe constructs and hardcoded credentials, and against the examples the caller supplies, without running it.
