What's in it

Data offered docs-verified
runtime code execution in the running Phoenix app (project_eval) · live app logs (get_logs) · development database SQL queries (execute_sql_query) · module/function source locations, including hex dependencies (get_source_location) · documentation pinned to mix.lock versions (get_docs)
Formats docs-verified
MCP streamable HTTP · MCP stdio
Access docs-verified
Open source under Apache License 2.0; installed as a dev-only hex dependency (tidewave ~> 0.9, only: :dev); no credentials documented in DOCS

Useful for

Use cases llm-inferred
Debug a failing code path in a Phoenix data or asset app against live dev state using project_eval · Read request logs and backtraces with get_logs when a Phoenix app misbehaves during development · Verify records written by a Phoenix app in the dev database with execute_sql_query · Jump to the definition of a function in a hex dependency with get_source_location instead of grepping
Audience llm-inferred
Elixir/Phoenix developers · web developers building internal Phoenix tools · GIS and data developers maintaining Phoenix apps

Limitations

Constraints docs-verified
Phoenix applications only · development-only: the plug is intended for Mix.env() == :dev · tools execute arbitrary Elixir and SQL against the running dev app and dev database · localhost-only by default; remote access needs the allow_remote_access option · works best with Phoenix LiveView v1.1 or later · worktrees need mix tidewave.proxy as a STDIO MCP · no geographic or hosted dataset; output reflects only the local app's state
