See what an agent can do with Insomnia before you ever sign up. Pick a story: recorded sessions replay real probe-harness transcripts; commands tagged live-capable can re-run against the real endpoint from our edge, right now (▶ run live — the exact same request, live and recorded lines always labeled); sandboxed self-drive sessions are designed and gated (docs/TRY-IT.md).

Opportunities — the stories that would move this product's scores, from its own judged verdictsOpportunitiestop 8 of 32 stories with headroom

What would move Insomnia’s scores — derived from its own judged verdicts, biggest headroom first. Each line quotes what the judge found missing; shipping it (or evidencing it publicly) is the fix.

  1. Agenticness — how well agents can access and operate the productConnect an agent via an official MCP server

    nonemoves agent-readyimpact 45

    Evidence shows Insomnia acts as an MCP *client* (docs-14, docs-30, docs-46) that connects to external MCP servers, not as an MCP server that an agent could connect to.

  2. Privacy posture — data-handling and privacy storiesPrevent my data from being used to train AI models

    nonemoves PA Scoreimpact 30

    Insomnia's docs describe AI features (mock generation, commit suggestions) and data-security claims about sync servers not reading project data, but there is no evidence of any control or policy letting users opt out of their data being used for AI model training.

  3. Agenticness — how well agents can access and operate the productSet up automations that run autonomously in the background

    nonemoves Built-in AIimpact 30

    Insomnia offers CI-triggered test automation via Inso CLI and manual Collection Runner runs, but there is no evidence of autonomous, self-scheduling background automations (e.g., cron-like triggers or agents running unattended) — all automation examples require an external CI pipeline or manual invocation.

  4. Agenticness — how well agents can access and operate the productIssue scoped/least-privilege API credentials for an agent

    nonemoves agent-readyimpact 30

    Insomnia offers RBAC for controlling access to its own resources, external vault integration for retrieving secrets, and environment variables for storing credentials, but there is no evidence of a feature to generate or issue scoped, least-privilege API credentials specifically for an AI agent to use.

  5. Agenticness — how well agents can access and operate the productBuild against official SDKs

    nonemoves agent-readyimpact 30

    Evidence shows Insomnia's automation surface is the Inso CLI and plugin system, plus MCP client support, but no official SDK (e.g., a Node/Python/Go SDK) for programmatically building against Insomnia is documented anywhere in the pack.

  6. Agenticness — how well agents can access and operate the productRely on versioned APIs with a documented deprecation policy

    nonemoves API qualityimpact 30

    The evidence pack shows Insomnia has versioned file/import formats (e.g., Insomnia JSON v4/YAML v5, OpenAPI 3.0/3.1) but there is no documentation of a formal versioning scheme or deprecation policy for any Insomnia-exposed API, plugin API, or CLI interface that an AI agent would rely on for stability guarantees.

  7. Agenticness — how well agents can access and operate the productDelegate tasks to a built-in AI assistant inside the product

    partialq4/10moves Built-in AIimpact 27

    Missing: evidence of a general conversational/agentic AI assistant embedded in the app, ability to delegate arbitrary tasks beyond mock/commit generation, and independent/hands-on confirmation of these AI features' quality.

  8. Agenticness — how well agents can access and operate the productDrive the product through a documented public API

    partialq4/10moves agent-readyimpact 27

    Missing: a documented HTTP/SDK-style public API for controlling Insomnia, independent confirmation the Inso CLI/plugin surface is used for AI-agent automation.
