Agent Security Scanner MCP vs Elasticsearch
A side-by-side look at the Agent Security Scanner MCP and Elasticsearch MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Agent Security Scanner MCP for security work as a local process; choose Elasticsearch 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 Agent Security Scanner MCP when
- You need dedicated capabilities in the Security domain.
- You prefer a local stdio subprocess transport.
- You want tools like
scan_security, fix_security, record_security_outcome.
Choose Elasticsearch when
- You need dedicated capabilities in the Security domain.
- You prefer a local stdio subprocess transport.
- You have the keys it needs:
ES_URL, ES_API_KEY, ES_USERNAME, ES_PASSWORD, ES_CA_CERT, NODE_TLS_REJECT_UNAUTHORIZED, MCP_TRANSPORT, MCP_HTTP_PORT. - You want tools like
list_indices, get_mappings, es_search.

Agent Security Scanner MCP tools 23
scan_securityScan a file for security vulnerabilities. Use verbosity='minimal' for counts only (~50 tokens), 'compact' (default) for actionable info (~200 tokens), 'full' for complete metadata.fix_securityScan a file and return fixes. Use verbosity='minimal' for summary only, 'compact' (default) for fix list, 'full' for complete fixed file content.record_security_outcomeRecord aggregate remediation outcomes after reviewing scanner findings. Sends counts only; never sends code, findings, paths, or rule IDs.list_security_rulesList all available security fix templates and their descriptionscheck_packageCheck if a package name is legitimate or potentially hallucinated (AI-invented)scan_packagesScan code for package imports and check for hallucinated (AI-invented) packages. Use verbosity='minimal' for counts, 'compact' (default) for flagged packages, 'full' for all details.list_package_statsList statistics about loaded package lists for hallucination detectionscan_agent_promptScan a prompt for malicious intent. Returns BLOCK/WARN/LOG/ALLOW. Use verbosity='minimal' for action only, 'compact' (default) for findings, 'full' for audit details.scan_git_diffScan git diff for new security vulnerabilities. Only reports issues on changed lines. Use for PR reviews.scan_projectScan an entire directory for security vulnerabilities with .gitignore support and security grading. Use verbosity='minimal' for grade + counts, 'compact' (default) for top issues, 'full' for all details.scan_agent_actionPre-execution security check for agent actions (bash, file_write, file_read, http_request, file_delete, cron, process_spawn, git, docker). Returns ALLOW/WARN/BLOCK.scan_mcp_serverScan an MCP server's source code for security vulnerabilities: overly broad permissions, missing input validation, data exfiltration, insecure patterns. Returns grade (A-F) and recommendations.- +11 more on the listing page

Frequently asked questions
Agent Security Scanner MCP is categorized under Security and uses a local stdio subprocess. Elasticsearch belongs to Security and uses a local stdio subprocess. Pick Agent Security Scanner MCP for security work and Elasticsearch 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.
Agent Security Scanner MCP has no declared pricing — check the project's own site. Elasticsearch has no declared pricing — check the project's own site. 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 agent-security-scanner-mcp and elasticsearch as separate keys in the same mcpServers object, and your assistant will call tools from either one.
