GET /v1/connectors – MCP directory API referenceMatching Connector Tools:
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.
Read-only MCP server for querying OkkMax measurements of AI API relay services, including model availability, observed prices, 24-hour uptime, latency, and model- and group-level purity evidence. No sign-in or API key is required.
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.
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.
See which AI models fall for traps in everyday jobs, and check or scan any MCP server, skill or package before your agent installs it. No sign-in; read-only; returns structured data.
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.
x402 endpoint doctor: grades a paid route A-F unpaid, with paste-ready fixes. By Crypto Money Maker
Grade MCP tool definitions for agent-readiness: score, A-F grade, fixes, est. token cost.
Traffic Parrot simulates APIs and messaging. Request or withdraw a trial, read docs, send feedback.
Pays your endpoint like a stranger would and signs a checkout conformance verdict.
Test and debug your AI agent's Web Bot Auth (RFC 9421) signature: is it valid, and what to fix?
Is this x402/MPP API safe to pay? $0.001 preflight, fixes, a $0.25 test purchase. Free quick check.
Refusal-dialect probe: signed cards naming what a server's 429 means and whether its meter lies.
Remote MCP that evaluates one public HTTPS URL for WebMCP readiness: intent, tools observed, what to add, what never to expose.
Free *.pntr.dev dev subdomains — register subdomains, manage DNS and wildcard records, receive email on disposable inboxes, and capture HTTP requests for webhook debugging. OAuth sign-in; free tier.
Retrieve YouTube transcripts with timestamps, native captions and asynchronous generation when captions are unavailable. Requires a Capslane API key.
Census and digest-verify a remote MCP server's loadable skills per host persona.
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.
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.
Live road conditions for the agent web: check a site or API before acting, report after.
Guide developers from setup through a verified, policy-aware, audited Alter API call.
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.
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.
Gemmein docs, API reference, error explainers and a live integration check for coding agents.
