Every tool call, across every MCP server.
MCP gives your agents hands. Obsivara watches what those hands do: every tool call across every MCP server, traced with arguments, duration, and outcome — plus a live inventory of which agents can reach which tools, resources, and systems.
MCP, fully observable.
Tool-call tracing
Every MCP tool invocation traced — which agent called which tool on which server, with what arguments, and what came back.
MCP server inventory
A live map of every MCP server in your estate, the tools and resources each exposes, and which agents and workflows depend on them.
Per-tool reliability metrics
Latency, error rates, and timeout patterns per tool — so a flaky MCP server gets caught before it degrades every agent that uses it.
Capability risk surface
See which tools grant write access to which systems, and which agents hold those capabilities — your agent blast-radius map.
Three steps. No code changes.
Register your MCP servers
Point Obsivara at your MCP server endpoints, or drop its observer into your MCP client configuration.
Traffic maps automatically
Tool calls, resources, and agent-to-server relationships appear as traffic flows — no manual cataloging.
Set tool-level policies
Alert on error spikes, unusual call patterns, or first-time use of high-privilege tools.
Signals tracked out of the box.
- →Tool calls per server, agent, and tool
- →Call arguments and result status

Common questions.
Which MCP transports are supported?
Both stdio and HTTP-based MCP servers are supported. Obsivara observes the protocol layer, so it works regardless of what the server is written in.
Can Obsivara block dangerous tool calls?
Obsivara is observe-and-alert by design — it flags unusual or high-privilege tool usage in real time, and feeds policy engines if you want enforcement elsewhere.
Does this work with third-party MCP servers I don't control?
Yes. Client-side observation traces calls to any MCP server your agents connect to, whether you run it or a vendor does.
