About this automation

Create a wrapper for MCP servers (local or remote) that monitors response sizes and forces agents to apply filtering when responses exceed a configurable threshold. Solves the problem where MCP servers return full accessibility snapshots instead of filtered CLI-style output, causing rapid context bloat.

How to implement

1

Identify MCP servers in your agent workflow that return large responses (e.g., playwright-mcp)

2

Measure baseline response sizes and token usage with benchmark suite

3

Implement MCP wrapper that intercepts responses before agent receives them

4

Add response size detection and threshold configuration

5

Implement filtering logic that forces agent to apply content filters on large responses

6

Test with both local and remote MCP servers

7

Benchmark token savings vs. overhead on representative tasks

8

Deploy wrapper in agent pipeline
