SqueezeOS MCP for x402-paid USDC APIs on Base. Flagship read settle-proven 2026-11-02 (SELF-PROOF).
Serverless 15-tool B2B email deliverability, domain security, OpenAPI breaking-change release gate, LLMO /llms.txt auditor, and quantitative trading risk MCP connector.
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.
Write, check, render and save sequence diagrams with the request and response on every arrow.

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.
Signed declarations of HTTP API exchanges for agent handoffs. Free preparation and verification; receipt issuance costs 0.002 USDC via x402 on Base. Start and connect: https://datoka.dev/api. Signatures attest declared data, not independent truth.
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.
Independent health, price and history for x402/MPP endpoints. Metered over x402; free grade on web.
Hosted mock APIs from OpenAPI, TypeScript or Postman: realistic data, errors and latency on demand.
Surface contracts: API behavior evidence, x402 pre-payment check, MCP server preflight
Find any agent service, and check it before you pay for it or rely on it.
Hands-on test results for 560+ remote MCP connectors: does it work, how to sign in, what breaks.
Free tools: x402 endpoint directory + probe, on-chain x402 demand signal, sudoku, API pricing.
Paid OpenAPI audit and API change detection for agents. $0.10 USDC per analysis via x402 on Base.
Debug webhooks from your AI agent: inspect and replay captured webhooks on localhost.
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.
