# Best Monitoring Tools for AI Agents (2026)

Uptime, logging, alerting, observability

| # | Tool | Grade | Score | Biggest Friction |
|---|------|-------|-------|-----------------|
| 1 | PagerDuty | B | 6.7 | Lack of an OpenAPI specification and no MCP server limits agent discoverability and integration—agents must rely on manual documentation parsing and custom SDK integration rather than automated schema discovery. |
| 2 | Grafana | B | 6.44 | Absence of webhooks, streaming, or reactive primitives forces agents to poll the API repeatedly, creating latency and inefficiency in responding to Grafana state changes. |
| 3 | New Relic | B | 6.44 | The absence of an OpenAPI specification, MCP server, or machine-readable API discovery mechanism (llms.txt/agents.json) forces agents to depend entirely on manual documentation parsing rather than automated schema discovery and validation. |
| 4 | Datadog | B | 6.32 | Lack of an OpenAPI specification and official MCP server makes it difficult for agents to discover Datadog's full API surface and integrate natively without manual endpoint mapping. |
| 5 | Honeybadger | B | 6.24 | Absence of an OpenAPI specification and MCP server prevents agents from automatically discovering API endpoints, methods, and schema requirements, requiring manual integration effort. |
| 6 | Axiom | C+ | 5.76 | Missing OpenAPI specification and robots.txt blocking agents severely limit discoverability and automated integration; agents must rely on SDK documentation rather than self-discovering API capabilities. |
| 7 | BetterStack | C+ | 5.22 | The absence of an OpenAPI specification and formal API documentation makes it difficult for agents to discover endpoints, understand response schemas, and integrate programmatically without manual investigation. |
| 8 | Highlight.io | C+ | 5.08 | Complete absence of OpenAPI specification or machine-readable API documentation (llms.txt, agents.json) prevents agents from autonomously discovering and understanding available endpoints, forcing reliance on human-maintained SDK documentation. |
| 9 | LogRocket | C | 4.54 | The absence of a public, documented REST API with OpenAPI specification makes it impossible for agents to discover endpoints, understand request/response schemas, or implement autonomous integration. |
| 10 | Checkly | C | 4.52 | The homepage 403 error and complete absence of OpenAPI documentation, llms.txt, agents.json, and accessible developer docs make it impossible for agents to autonomously discover, understand, and integrate with Checkly's API. |
