Reversecore MCP vs Semgrep
A side-by-side look at the Reversecore MCP and Semgrep MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Reversecore MCP for security work as a local process; choose Semgrep for security as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Reversecore MCP when
- You need dedicated capabilities in the Security domain.
- You prefer a local stdio subprocess transport.
- You want tools like
audit_source_code, run_file, copy_to_workspace.
Choose Semgrep when
- You need dedicated capabilities in the Security domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: No auth required.

Tools & capabilities
Reversecore MCP tools 114
audit_source_codePerform a security audit on a source code file (SAST). This tool analyzes source code (C, C++, Python, Go, etc.) to identify potential security vulnerabilities such as buffer overflows, injection flaws, and weak cryptography. It provides a structured breakdown of dangerous patterns found in the code to guide deeper manual or AI-driven analysis. Use this tool when you have access to original source code or when you want to analyze decompiled output exported to a file.run_fileIdentify file metadata using the ``file`` CLI utility.copy_to_workspaceCopy any accessible file to the workspace directory. This tool allows copying files from any location (including AI agent upload directories) to the workspace where other reverse engineering tools can access them. Supports files from: - Claude Desktop uploads (/mnt/user-data/uploads) - Cursor uploads - Windsurf uploads - Local file paths - Any other accessible locationcreate_directoryCreate a new sub-directory within the workspace. This tool allows AI agents to dynamically create isolated sub-workspaces for different tasks or sessions.list_workspaceList all files in the workspace directory. Returns: ToolResult with list of files in workspacescan_workspaceBatch scan all files in the workspace using multiple tools in parallel. This tool performs a comprehensive scan of the workspace to identify files, analyze binaries, and detect threats. It runs 'run_file', 'parse_binary_with_lief', and 'run_yara' (if rules exist) on all matching files concurrently. **Workflow:** 1. Identify files matching patterns (default: all files) 2. Run 'file' command on all files 3. Run 'LIEF' analysis on executable files 4. Run 'YARA' scan if rules are available 5. Aggregate results into a single reportexplain_patchAnalyze differences between two binaries and explain changes in natural language. This tool combines binary diffing with decompilation to help understand security patches. It identifies changed functions, decompiles them, and uses heuristics to explain the nature of the changes (e.g., "Added bounds check", "Replaced unsafe API").assemble_instructionsAssemble assembly instruction strings into raw machine byte values using Keystone.create_memory_sessionCreate a new memory session to store memories. Use this when starting a new reverse engineering analysis. The session name should be descriptive and follow a template format like 'malware_analysis_2024_001' or 'game_cheat_detection'.save_memory_itemSave important information to long-term memory. Use this to remember: - Function addresses and their purposes - Vulnerability patterns discovered - API call sequences - User instructions and preferences - Interesting strings or structuresrecall_memory_itemSearch and recall memories from past analyses. Use this when you need to remember something from earlier, or when the user asks about previous findings.list_memory_sessionsList all analysis sessions with timestamps and status. Use this to see what analyses have been done before, or to find a session to resume.- +102 more on the listing page

Frequently asked questions
Reversecore MCP is categorized under Security and uses a local stdio subprocess. Semgrep belongs to Security and uses a local stdio subprocess. Pick Reversecore MCP for security work and Semgrep for security.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Reversecore MCP has no declared pricing — check the project's own site. Semgrep is listed as free. Auth: no auth required. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add reversecore-mcp and semgrep-semgrep as separate keys in the same mcpServers object, and your assistant will call tools from either one.
On AllMCPs, Reversecore MCP has a quality signal of 63/100 (Good) with 2 views, 0 installs and 211 GitHub stars. Semgrep has 48/100 (Fair) with 1 views, 0 installs and 17,146 GitHub stars.
