Explore extension filter points across MCP adapter handlers #130
Description
We should investigate where additional filter hooks would be most valuable across the MCP adapter request flow. The goal is to identify safe, well‑documented extension points for downstream integrations without changing default behavior.
Scope (exploration):
- Map the handler lifecycle (initialize, tools, resources, prompts, system, transport).
- Identify where inputs/outputs are assembled and serialized.
- Propose candidate filters (pre‑sanitization, post‑sanitization, pre‑response, post‑response).
Deliverable:
- A short proposal with recommended filter points, rationale, and example use cases.
