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.
Look up 133 agentic-web standards, live-probe any domain, validate manifests, generate boilerplate.
Danish company data from CVR: owners, management, accounts, credit risk, court cases, bankruptcies.
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.
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.
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.
Scores how well AI agents will use your API, 0-100, from its OpenAPI spec. Free and read-only.
Remote MCP that evaluates one public HTTPS URL for WebMCP readiness: intent, tools observed, what to add, what never to expose.
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.
Migrate custom GPT Actions (OpenAPI) to MCP: preview conversions, setup steps, retirement checklist
Check an x402 endpoint before you pay it, then test a payment and follow it to settlement.
