Elastic (ELK Stack) REST API
Elastic REST API for Elasticsearch, Kibana, and the ELK Stack observability and search platform. Enables AI agents to perform full-text and vector search across indexed documents, handle log analytics and query (EQL/KQL/Lucene) workflows, access Elastic Security SIEM detection rules and alerts, retrieve observability APM traces and metrics, manage index and data stream lifecycle, handle machine learning anomaly detection and classification, access Elastic AI Assistant integration, retrieve Kibana dashboard and visualization data, manage Elasticsearch cluster health and node management, and integrate search and analytics with data pipelines and applications.

🔒 Security
Search and log data. SOC2, ISO27001, FedRAMP, HIPAA, PCI-DSS. API key with RBAC. Global. Document-level security for fine-grained access.
⚡ Reliability
Best When
An engineering team using Elastic Cloud or self-hosted ELK Stack wants AI agents to automate search queries, log analytics, SIEM alert management, vector search for RAG pipelines, and ML-based anomaly detection.
Avoid When
SECURITY: Elasticsearch indexes may contain PII, credentials, and sensitive application data. Open Elasticsearch ports without authentication is a common misconfiguration that exposes data publicly. SIEM data access must be strictly scoped. Vector search over sensitive embeddings requires data classification and access controls.
Use Cases
- • Performing full-text and semantic vector search from knowledge retrieval agents
- • Accessing log analytics and observability data from monitoring automation agents
- • Querying SIEM detection alerts from security operations agents
- • Integrating Elasticsearch search with RAG pipelines from AI application agents
Not For
- • Simple key-value lookups without full-text or vector search requirements
- • Non-technical teams without Elasticsearch query DSL learning curve tolerance
- • Real-time operational data without the ELK infrastructure investment
Interface
Authentication
Elastic uses API keys with document-level and field-level security for fine-grained access control. Elastic Cloud uses API keys and SSO. Role-based access control (RBAC) for index and cluster permissions. Official MCP server (elastic/mcp-server-elasticsearch). SDKs for Python, JavaScript, Java, Go, Ruby, PHP, .NET, Rust. OpenAPI spec available.
Pricing
San Francisco, California. NYSE: ESTC. Founded 2012. Pioneer in search-based analytics. $1.3B+ annual revenue. 20,000+ customers. Elasticsearch is most popular enterprise search and analytics engine. ESRE (Elastic Relevance Engine) for semantic and hybrid search. Competes with Splunk for SIEM and Datadog for observability.
Agent Metadata
Known Gotchas
- ⚠ SECURITY: Open Elasticsearch without auth is a critical misconfiguration — always use API keys with RBAC even for internal clusters
- ⚠ Query DSL complexity — Elasticsearch query language has steep learning curve; use official Python client for agent integrations
- ⚠ Official MCP server available (elastic/mcp-server-elasticsearch) — strongly prefer over raw REST for agent use
- ⚠ Document-level security for fine-grained access — configure per-index API key restrictions for agent scope
- ⚠ Vector search (kNN) requires ML node or serverless — verify cluster configuration supports vector search
- ⚠ Index mapping changes require reindexing — automated index management by agents can cause data migration complexity
