ping

Verify connectivity to the REAPER bridge by checking reachability and returning version information for both bridge and REAPER software.

Implementation Reference

  • Reaper adapter ping method that calls the underlying bridge client.
    def ping(self) -> dict[str, Any]:
        return self._client.call("ping")
  • MCP tool definition and registration for the 'ping' tool.
    @mcp.tool()
    def ping() -> dict[str, Any]:
        """Check that the bridge is reachable. Returns bridge_version and reaper_version."""
        try:
            return _wrap(adapter.ping())
        except Exception as exc:
            return _err(exc)
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. Discloses return values (bridge_version, reaper_version) which helps predict output. 'Check' implies read-only safety, but lacks explicit non-destructive/idempotent confirmation or error behavior (what happens if unreachable).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, zero waste: first states purpose, second states return values. Appropriately front-loaded and sized for a trivial health-check tool.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Sufficient for a zero-parameter health check. Mentions return values (complementing the unspecified output schema content). Could explicitly state 'safe to call anytime' given lack of safety annotations, but adequate for simple ping.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Zero parameters per schema. Baseline 4 applies. Description correctly implies no inputs needed for a ping operation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Specific verb 'Check' + resource 'bridge' clearly defines the reachability test. Distinct from 40+ operational siblings (add_fx, create_track, etc.) which manipulate the DAW rather than testing connectivity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Implies use as a health check via 'reachable', but lacks explicit when-to-use (e.g., 'call first to verify connection') or when-not-to-use guidance. No alternatives named, though 'ping' conventionally stands alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
