Overview

AI-generated overview

An AI-native mock API server that lets an assistant create REST and SOAP mocks from Claude, Cursor, or Windsurf.

What you can do
Simceptor is a hosted mock API service with an MCP interface. According to its registry description, it lets an assistant create REST and SOAP mock endpoints directly from supported AI clients such as Claude, Cursor, or Windsurf. No individual tools are listed in the manifest, so the exact operations are not documented here.
When to use it
Useful when you want an assistant to stand up mock REST or SOAP APIs for prototyping or testing without building a backend by hand, and you already work in one of the supported clients.
Requirements
A remote MCP endpoint at simceptor.com over streamable HTTP. Authentication is required via OAuth. No environment variables or headers are declared.
Before you install
The server requires OAuth sign-in, so it will receive account credentials through that flow. It creates mock API resources on a hosted service, meaning the endpoint definitions you ask for are stored remotely. Review what data you send before creating mocks.

Installation

In SourceWeft

  1. Open Simceptor in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.ayda212%2Fsimceptor/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
