Test what your agent says and does.

Build confidence in your agent’s behavior. Mibo checks recorded responses and tool calls against your rules and shows the evidence behind the results.

Agent replied to the customer
Tone and wording check passed

Correct wording. Broken refund rule.

Send your first trace
Configure an OTLP exporter and capture an execution from your system.
Generate a test with AI
Select a completed trace and ask AI to draft checks from its evidence. Review the draft before saving it.
Evaluate future traces
Send later executions and inspect which checks failed, together with the recorded response or action.

Exporter example

Instrument your application, replace the API key placeholder, and match the service name configured in Mibo. OTLP/HTTP JSON is also supported.

Mibo only Multiple destinations

Send traces directly from your instrumented application to Mibo.

export OTEL_EXPORTER_OTLP_TRACES_PROTOCOL=http/protobuf
export OTEL_EXPORTER_OTLP_TRACES_ENDPOINT=https://api.mibo-ai.com/public/traces
export OTEL_EXPORTER_OTLP_TRACES_HEADERS='x-api-key=<YOUR_API_KEY>'
export OTEL_SERVICE_NAME='your-service-name'

Send traces to an OpenTelemetry Collector and configure it to forward them to Mibo and your existing destination.

Application exporter

export OTEL_EXPORTER_OTLP_TRACES_PROTOCOL=http/protobuf
export OTEL_EXPORTER_OTLP_TRACES_ENDPOINT=http://127.0.0.1:4318/v1/traces
export OTEL_SERVICE_NAME='your-service-name'

Collector configuration

receivers:
  otlp:
    protocols:
      http:
        endpoint: 127.0.0.1:4318
exporters:
  otlp_http/mibo:
    traces_endpoint: https://api.mibo-ai.com/public/traces
    headers:
      x-api-key: ${env:MIBO_API_KEY}
  otlp_http/other:
    traces_endpoint: '<YOUR_OTHER_OTLP_HTTP_TRACES_ENDPOINT>'
service:
  pipelines:
    traces:
      receivers: [otlp]
      exporters: [otlp_http/mibo, otlp_http/other]

Set MIBO_API_KEY in the Collector environment. The other destination may need its own credentials. 127.0.0.1 requires the app and Collector to share a network namespace. Adjust existing exporter headers for the Collector; endpoint variables accept one URL, not a comma-separated list.

You can also configure multiple exporters in your SDK.

Questions about Mibo

What does Mibo evaluate?

Mibo checks recorded answers, tool calls, and values against the rules you configure, using the data in each trace.

Which systems can send traces?

Any system able to send compatible OTLP traces can submit recorded executions to Mibo.

What if a check needs missing data?

A missing field does not prove that a check passed. Add the required data to your instrumentation; the result depends on the check.

Does Mibo intervene in the interaction?

No. Mibo evaluates received traces; it does not block or undo the actions they record.
