Adapter Compatibility Matrix

This matrix tracks every known DCC-MCP adapter, its core version pin, adapter version, and supported DCC version range. It should match the adapter entries in dcc-mcp-catalog.yml, because dcc-mcp-cli install --dcc-type <dcc> uses that catalog as its first-party install source. Every adapter release must submit a PR updating this matrix before the release PR merges.

How to Add a New Adapter

1. Find the next empty row in the table below.
2. Fill in every column with the adapter's latest released values at the time of the PR.
3. Submit the PR against docs/guide/adapter-compatibility-matrix.md.

How to Update an Existing Adapter

1. Change the Adapter Version and/or Core Pin columns to match the new release.
2. Update Last Verified to the date the release smoke was run.
3. If the DCC minimum version changed, update DCC Min Version.

Column Reference

Column	Description
DCC	Canonical DCC name (lowercase, kebab-case).
Repository	GitHub URL for the adapter source code.
Adapter Version	Latest released semver of the adapter.
Core Pin	Dependency range for dcc-mcp-core. Must exclude <1.0.0 until core reaches 1.0.
DCC Min Version	Minimum host version (e.g. 2024+, 3.6+, 20.5+).
Dispatcher Pattern	A short summary of the adapter's runtime routing model, such as Qt sidecar, Event-loop callback, InProcessCallableDispatcher, diagnostics-only sidecar, or an external bridge. See skills/dcc-mcp-creator/references/HOST_PATTERN_MATRIX.md for details.
Last Verified	Month the last gateway smoke was run (format: YYYY-MM).

Core Version Policy

• Adapters must pin dcc-mcp-core with an open upper bound: >=X.Y.0,<1.0.0.
• The lower bound (X.Y.0) must be a released minor version of core. Never pin to main or a pre-release.
• When core bumps its minor version, adapter pins should be updated within one adapter release cycle.
• Major version zero (0.x.y) means breaking changes can happen at any minor bump; the <1.0.0 guard ensures adapters don't silently consume a breaking core change.

Legend

Marker	Meaning
⏳	Release tag pending — adapter PR in review, version subject to change. Remove marker after tag.

CLI Catalog Contract

dcc-mcp-catalog.yml is the install source for first-party adapters. When an adapter row above changes, update the matching catalog entry in the same PR:

• name, url, version, and min_core_version must match this matrix.
• Adapter rows must have the adapter tag and install metadata.
• Adapter install metadata should include instructions_url pointing at the adapter-maintained raw install.md so dcc-mcp-cli install can hand agents the current host-specific setup runbook.
• Skill pack rows may share the same dcc, but must not be selected by dcc-mcp-cli install --dcc-type <dcc> when an adapter row exists.

Outdated Policy

An adapter row is considered stale when:

• Last Verified is more than 6 months old, or
• Core Pin lower bound is more than 2 minor versions behind the latest core release.

Stale rows are flagged in the core release PR notes. Adapter maintainers should prioritise a compatibility update before the next core release.
