agent: mcp

When does this happen?

IF Schema validation fails with EvalError in Cloudflare Workers when using the elicitation feature due to AJV v6 dynamic code generation.

How others solved it

THEN Replace AJV v6 with a JSON Schema validator compatible with edge environments, such as AJV v8 with interpreted mode (code: { source: false }) or @cfworker/json-schema. Additionally, provide a configuration option or hook to allow users to supply their own validator, making the SDK more flexible for different environments.

new Ajv({ code: { source: false } })
