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

GXEON services, prepaid packs from R$0.99, purchase planning, and agent buyer guidance.
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.
Detect breaking changes, generate changelogs, diff, and validate OpenAPI specs.
Check an x402 endpoint before you pay it, then test a payment and follow it to settlement.
