fix_bug
shallowio.github.fetchsandbox/mcp · Verify this server
FetchSandbox remediation: get a proposed fix for a specific bug in YOUR code. The 'fix' step after find_bugs. Ships the project to the FetchSandbox runtime, which authors a MINIMAL fix grounded in the known remediation for that failure class and returns a git diff — it does NOT modify your files, so review the diff and apply it yourself. IMPORTANT: the diff is a proposal, not a proof. After applying it, prove the fix (submit_proof / verify_behavior) so the buggy→fixed flip is measured, not assumed. Runs for up to a few minutes.
