Find the bugs that drain accounts,
not the ones that fail a linter.

OSE Auditor builds a state-transition graph of every function and applies deterministic signatures for broken auth, double-spend races, unchecked external calls, and settlement bypass - before any of it reaches production.

MCP INTEGRATION

Runs inside Claude Code, Cursor, and Cline

OSE Auditor ships an MCP server so your AI coding assistant can run a security audit as a tool call - without leaving the editor. Add this to your .claude/settings.json:

        {

          "mcpServers": {

            "ose-auditor": {

              "command":
        "ose-mcp",

              "env": {

                "OSE_API_KEY": "ose_sk_your_key_here"

              }

            }

          }

        }
