Read one operation from a public OpenAPI document: method, path, and required fields.
Turn any public webpage into JSON with AI, save it as a live JSON API, and call it from your agent.
A webhook inbox for agents: one call returns a live URL. Mock, verify, inspect and replay.
Behind Check and GAIP Watch, and Diagnose: A2A, MCP and OpenAPI checks with a dated change log.
Simceptor is an AI-native Mock API simulation platform with a built-in MCP server. It enables AI agents to create, inspect, update, and test dynamic mock APIs, conditional response rules, stateful session simulations, and network latency directly from context.
Contract-change authorization for AI agents: preflight a change to an API or MCP contract, get a signed decision, and verify the receipt offline. Only a granted change can proceed.
Grade MCP tool definitions for agent-readiness: score, A-F grade, fixes, est. token cost.
x402 endpoint doctor: grades a paid route A-F unpaid, with paste-ready fixes. By Crypto Money Maker
Traffic Parrot simulates APIs and messaging. Request or withdraw a trial, read docs, send feedback.
Is this x402/MPP API safe to pay? $0.001 preflight, fixes, a $0.25 test purchase. Free quick check.
Test and debug your AI agent's Web Bot Auth (RFC 9421) signature: is it valid, and what to fix?
Pays your endpoint like a stranger would and signs a checkout conformance verdict.
Remote MCP that evaluates one public HTTPS URL for WebMCP readiness: intent, tools observed, what to add, what never to expose.
Refusal-dialect probe: signed cards naming what a server's 429 means and whether its meter lies.
Retrieve YouTube transcripts with timestamps, native captions and asynchronous generation when captions are unavailable. Requires a Capslane API key.
Point Claude Code, Qwen Code, Cursor, or any MCP client at https://docs.jmeter.ai/api/mcp and your agent answers JMeter questions grounded in this documentation, with a source link for every answer. Free, no API key, no signup.
Census and digest-verify a remote MCP server's loadable skills per host persona.
API documentation drifts away from the running service, so consumers integrate against a contract nobody keeps. Routebase keeps API design, testing, mocking and documentation on one living source of truth, and this MCP server exposes that workspace to AI agents. Agents can design endpoints, write and run test suites, manage mock servers and publish documentation, always under the permissions of the connected Routebase account.
Check an x402 endpoint before you pay it, then test a payment and follow it to settlement.
Guide developers from setup through a verified, policy-aware, audited Alter API call.
Live road conditions for the agent web: check a site or API before acting, report after.
Gemmein docs, API reference, error explainers and a live integration check for coding agents.
MCP endpoint to APIbase catalog (https://apibase.pro/llms.txt). USDC: x402 Base, MPP Tempo.
Trickl for AI assistants: full docs, setup plans, and sandbox tools to test purchases end to end.
Lints whether a paid API's 402 response speaks the x402 protocol correctly.
What is known to be broken in an MCP server or API operation, with the check that found it.
Audits a sample of HTTP request URLs against explicit, documented cache-key standardization rules...
Independent checks of paid x402 data sellers and of AI-agent access to shopping and travel sites
Generates deterministic webhook HMAC-SHA256 fixtures and optionally verifies a supplied signature...
Webhook capture bins for agents: get a URL, wait for webhooks, set replies, verify signatures.
Ephemeral mailboxes and a mock OAuth IdP for testing email and auth flows — 39 API-driven tools covering mailboxes, mails, attachments, domains, teams, and mock identities.
MCP server that delivers up-to-date Bitrix24 REST API documentation.
An MCP server that provides tools to validate an email address using Dilli Email Validation API.
Check whether a URL can be opened. No browser is launched.
Whether a token is an HTTP method
Public benchmark where agents submit Q&A answers and get scored on a leaderboard.
Free platform to test MCP clients without installing anything. Create mock tools with dynamic templates, configurable delays, conditions (if/then), and response sequences. Supports JSON-RPC 2.0 over Streamable HTTP. Built-in text_echo and json_echo tools. Rate-limited tiers: anonymous (5 calls/min, 1 mock tool), registered (10 calls/min, 4 mock tools), premium (60 calls/min, unlimited). Zero setup — no install, no registration required.

Hosted MCP infrastructure with seven typed tools: JSON repair, JSON Schema validation, JSON to TypeScript, CSV to JSON, JSON to CSV, OpenAPI security and webhook checks. Public tool discovery; execution uses scoped Bearer keys with tool allowlists, quotas and request IDs. Free deterministic calls, no LLM calls or USDC payments. Runnable repair → validate → CSV example: https://invokeport.com/agents/workflows/json-pipeline. MCP through 2025-11-25; custom headers, no OAuth.
Hands-on test results for 560+ remote MCP connectors: does it work, how to sign in, what breaks.
