re-mitm2swagger
MCP server for REST API reverse engineering from HTTP traffic captures. Wraps mitmproxy for live capture and mitmproxy2swagger for spec derivation.
Tools
Tool | What it does |
| Confirm mitmdump is on PATH |
| Spawn mitmdump in the background |
| Stop a previously-started capture |
| Read a mitmproxy flow file |
| Convert HAR → OpenAPI 3.0 spec (with path templating) |
| mitmproxy2swagger on a flow file → OAS |
| Filter flows by method/host/path/status/content-type |
| Heuristically find tokens, JWTs, API keys |

Install
pip install mitmproxy mitmproxy2swagger
pip install -e ./servers/re-mitm2swaggerWhy this matters
Most mobile apps and SPAs talk to a REST API. The fastest way to understand the API surface is to capture traffic, then derive the spec. mitmproxy handles the capture, mitmproxy2swagger handles the spec — this server glues them together with secrets detection and filtering.
