Backend engineer working on MCP, agent tooling and RAG.
I fix the small failures that make AI tools unreliable: authentication, pagination, streaming and resource cleanup.
专注 AI 工具与 Agent 基础设施，做能复现、能验证的修复。
A few fixes accepted upstream in MCP Go:
| Problem | Change | Pull request |
|---|---|---|
| Dynamic OAuth registration omitted the application type. | Send application_type in the registration request. |
#1003 · merged Oct 22, 2026 |
| Authorization callbacks needed to stay tied to the transaction that started them. | Bind callbacks to their initiating authorization transaction. | #1006 · merged Oct 22, 2026 |
| Resources with the same name could be missed during pagination. | Handle the cursor tie-break and legacy name-only cursors. | #991 · merged Oct 13, 2026 |
| A recognized modern discovery response could still fall back to the legacy handshake. | Avoid legacy initialization after modern discovery. | #997 · merged Oct 13, 2026 |
| Tool | What it does | Try it |
|---|---|---|
| HAR Triage | Turns a local HAR capture into an offline report of failed and slow requests, linked to the original entry indexes. | Synthetic demo and CLI |
| HTTP Probe | Gives a Harness agent an HTTP status, header latency and selected response headers without reading the body. Supports cancellation and a GET fallback when HEAD is unsupported. | Install in Harness |
| SheetDiff | Compares CSV or XLSX files by a business key. Review changed values, types, formulas and stored results in a local HTML report. | Run the synthetic demo |
HAR Triage and SheetDiff also run as standalone CLIs. Their examples use synthetic data and need no model call. SheetDiff compares stored formula results without editing workbooks or recalculating formulas.
I start with a reproducible failure, keep the fix focused, and add a regression test. I use AI assistance for development and review, with disclosure according to each project's policy.
Most of my code is Go, TypeScript and Python. I am currently focused on MCP clients, agent SDKs and the developer tools around them.
