MCP SDK Migration: 1.21.0 → 1.22.0

Issues Found

1. Type Safety: Missing as const in x402.ts

packages/agents/src/mcp/x402.ts:95-96, 131-132

The x402 integration inconsistently applies type literals. While outer objects use as const, inner content type fields don't:

return {
  isError: true,
  _meta: { "x402/error": payload },
  content: [{ type: "text", text: JSON.stringify(payload) }]  // Missing 'as const'
} as const;

This differs from the pattern used elsewhere (e.g., worker.ts:77, mcp-worker-authenticated/src/index.ts:46). Should be:

content: [{ type: "text" as const, text: JSON.stringify(payload) }]

2. Missing Test Coverage: x402 Integration

No dedicated test file exists for packages/agents/src/mcp/x402.ts despite handling critical payment flows:

• Payment verification
• Token decoding
• Settlement logic
• Client-side confirmation flows

The migration to registerTool API in this file is untested.

3. Breaking Change Uncommented

packages/agents/src/tests/worker.ts:51-52

// disable because types started failing in 1.22.0
// elicitation: { form: {}, url: {} }

Elicitation capability was disabled due to type failures but lacks:

• Root cause investigation
• Migration path documentation
• Issue tracking

4. Inconsistent Type Safety Across Examples

Files inconsistently apply as const to type: "text" fields. Some use it (worker.ts, mcp-worker-authenticated), others don't (x402-mcp, mcp/server.ts). This risks type widening from "text" literal to string.

Recommendations

1. Add as const to all type: "text" literals in x402.ts
2. Create packages/agents/src/tests/mcp/x402.test.ts
3. Investigate elicitation type failure or document as known breaking change
4. Standardize as const usage across all registerTool callbacks

Migration Pattern: ✅ The core API migration from server.tool() to server.registerTool() is correctly implemented across all files.
