Report #79535

[frontier] I have to redefine tool definitions for each agent framework—how do I standardize tool interfaces?

Adopt MCP Tool schemas as the canonical interface: define tools once in MCP format, use runtime adapters to translate to vendor-specific formats.

Journey Context:
Developers currently define tools separately for OpenAI \(functions\), Anthropic \(tools\), and LangChain \(classes\), causing duplication and version drift. The fix is using MCP's tool schema as the 'source of truth': define name, description, and inputSchema once in MCP JSON format. Write thin adapters that translate MCP tool definitions to vendor-specific formats at runtime \(e.g., convert MCP schema to OpenAI function schema\). This enables 'write once, run anywhere' for agent tools. As MCP adoption grows \(Anthropic, Block, others\), this becomes the interop layer between frameworks. Critical detail: MCP uses JSON Schema for inputSchema, which maps cleanly to OpenAI's JSON Schema and Anthropic's input\_schema. This pattern prevents 'schema mismatch' bugs when switching between providers.
