v1.1.5

What's Changed

• chore: prepare mcp-comet release with branding and docs refresh by @OneStepAt4time in #10

Full Changelog: v1.1.4...v1.1.5

v1.1.4

Full Changelog: v1.1.3...v1.1.4

v1.1.3

Fixed

• CLI Wrapper: Added comet_wait to the allowed tools list in src/cli.ts, fixing the 'Unknown tool' error when called via the command line.

v1.1.2

Fixed

CI/CD: Cleaned up unused variables and parameters in \src/server.ts\ to satisfy strict linting requirements in the CI pipeline.
Code Quality: Resolved
Unused Variables and ExplicitAny warnings in internal scripts.

v1.1.1

Fixed

• Screenshot Format (Issue #1, PR #6): Correctly handles MCP error responses during screenshots to prevent false-positive failures on transient connection drops. \comet_screenshot\ explicitly documents \jpeg\ support.
• Protocol Violation in \comet_ask\ (Issue #2, PR #7): Decoupled the polling loop from \comet_ask\ to prevent MCP transport timeouts (60s) during deep research tasks. The tool now submits the prompt and returns immediately; clients should use \comet_poll\ or \comet_wait\ to retrieve the final result.
• Aggressive Health Check (Issue #3, PR #8): Increased the \isHealthy\ CDP evaluate tolerance from 3s to 10s to prevent aggressive reconnections when Comet is busy rendering heavy React hydration tasks.
• Brittle State Detection Heuristics (Issue #4, PR #9): Removed fragile English text heuristics (e.g., 'Ask a follow-up') from the agent status detection script (\status.ts). It now reliably determines completion based on the structural presence of parsed prose chunks (
  esults.length > 0).

v1.1.0

What's New

comet_wait tool

New tool that polls until the agent finishes responding. Use after comet_ask times out to continue polling for the full response. Includes stall detection and response stabilization.

Typeahead-based mode detection

comet_mode (get) now opens the typeahead menu to read the active mode from SVG icons — works for all modes including deep-research, not just URL-based computer detection.

Collapsed citation expansion

comet_get_sources now automatically clicks collapsed citations (e.g., wsj+3) to reveal hidden source URLs. Second-pass extraction merges expanded links into results.

13 tools total (was 12)

Tool	Description
comet_connect	Connect to or launch Comet browser
comet_ask	Send prompt and poll until response
comet_poll	Get agent status, steps, and response
