Mockmcp
Prototype agent flows against realistic fake CRM, commerce, and user data via a hosted MCP URL without wiring real APIs.
Overview
io.github.K-Cupples/mockmcp is a Validate-phase hosted MCP server that exposes 12 fake-data tools over HTTPS for agent prototyping without backend setup.
What is this MCP server?
- Hosted streamable-http endpoint at https://mockmcp.io/mcp—no local server install
- 12 MCP tools with realistic fake datasets for agent scenarios
- Zero API keys or OAuth setup for the mock tier described in the registry
- Speeds up demos, evals, and Cursor/Claude Code spikes before backend contracts exist
- Version 0.1.0 with GitHub source at K-Cupples/mockmcp
- 12 MCP tools documented in the server description
- Remote URL https://mockmcp.io/mcp (streamable-http), version 0.1.0
What problem does it solve?
Early agent ideas stall because every demo needs real API keys, seed data, and fragile sandboxes.
Who is it for?
Solo builders pitching or iterating on agent SaaS before production integrations exist.
Skip if: Production workloads, compliance-sensitive data, or contract testing against real vendor behavior.
What do I get? / Deliverables
You can run credible multi-tool agent demos and prototypes the same day you add the remote MCP URL to your client.
- Working agent demos against 12 mock tools
- Faster scope validation before real API contracts
- Repeatable prototype sessions without seed scripts

Journey fit
Fake-but-realistic backends belong in validate when you are proving an agent product idea before committing to production integrations. Prototype is the right shelf because mockmcp exists to exercise tool-calling and UX paths, not to ship live customer data.
How it compares
Hosted fake-data MCP playground, not a secrets vault or design-model router.
Common Questions / FAQ
Who is mockmcp for?
Indie builders and small teams prototyping MCP agents who need plausible tool results without provisioning real SaaS accounts.
When should I use mockmcp?
Use it in validate/prototype when you want to test prompts, tool chains, and UX before locking API integrations.
How do I add mockmcp to my agent?
Register the remote MCP server URL https://mockmcp.io/mcp as streamable-http in Claude Code, Cursor, or your MCP client—no npm install required for the hosted endpoint.
