WebMCP for Agents

WebMCP is a browser-first MCP environment that is useful for testing and teaching agent tool workflows.

For Tandem teams, it is a fast way to:

  • prototype MCP server behavior before production wiring
  • validate tool contracts and payload shape
  • demonstrate agent-safe tool patterns to contributors

Why It Helps Tandem Engine Users

When you are building agent flows around tandem-engine, WebMCP can shorten iteration loops:

  • verify MCP tool schemas and outputs quickly
  • catch naming and argument mismatches before routines/run plans depend on them
  • onboard new teammates by showing live tool-call behavior

Suggested Tandem Workflow

  1. Build and validate MCP tools in WebMCP.
  2. Register/connect the same MCP server in Tandem (/mcp, /mcp/{name}/connect).
  3. Confirm namespaced tool IDs via /mcp/tools and /tool/ids.
  4. Restrict production automation with explicit allowed_tools on automations (routines/* is still supported).

Good Practices

  • Keep tool names stable once routines depend on them.
  • Prefer narrow, explicit allowed_tools for autonomous runs.
  • Treat WebMCP as a rapid validation environment, then enforce policy in Tandem.
