binary-ninja-headless-mcp
Provides a headless MCP server for Binary Ninja, exposing a large tool surface (analysis, disassembly/IL, patching, types/metadata, undo/redo, memory operations, scripting, and more) over stdio and TCP transports, including a fake backend mode for CI/dev without a Binary Ninja license.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
MCP is unauthenticated by default and exposes powerful mutation/scripting capabilities (binja.eval/binja.call, memory read/write, patching). README advises not to expose directly to untrusted users or networks; strong isolation is required. TLS/transport security for TCP is not described.
⚡ Reliability
Best When
Used in a trusted, containerized/sandboxed environment with co-location of the agent and this MCP server.
Avoid When
Avoid exposing it to untrusted users/networks without additional isolation and transport-level protections.
Use Cases
- • Automating reverse-engineering workflows with an MCP-capable agent
- • Programmatic disassembly/IL inspection and analysis progress management
- • Iterative patching and metadata/type/symbol refinement with transaction/undo/redo patterns
- • Running custom Binary Ninja scripting via an eval/call tool bridge
- • CI testing and tool-surface fuzzing using a fake backend mode
Not For
- • Untrusted or internet-facing deployments (server is unauthenticated by default)
- • Scenarios requiring enterprise APIs or debugger integration (explicitly not covered)
- • Environments where arbitrary scripting execution is disallowed
Interface
Authentication
MCP communication (stdio/TCP) is unauthenticated by default per README security model; no API keys/OAuth described.
Pricing
No hosted pricing described; requires a Binary Ninja headless-capable license for real operation, with a fake backend mode for development/CI.
Agent Metadata
Known Gotchas
- ⚠ TCP/stdio transports are unauthenticated by default; ensure isolation when using TCP.
- ⚠ Some operations mutate analysis state; rely on undo/redo/transactions and session safety modes to avoid unintended changes.
- ⚠ Scripting tools (binja.eval/binja.call) can execute arbitrary code paths within the Binary Ninja context; agents should restrict usage to trusted workflows.
- ⚠ tools/list defaults to returning the full catalog when pagination params are not provided, which may be large.
