OverviewDiscussionsAdmin

Probe an MCP server for available tools

probeMcpServer

Probe an MCP server URL and list the tools it exposes. Useful as a dry-run before creating a connection — verifies the URL is reachable, that authentication headers (if any) are correct, and surfaces the tool catalog. Performs no writes; sits alongside /v2/teams/:team_id/connections/oauth/mcp/check (which probes the same URL for OAuth support).

Input Schema

NameRequiredDescriptionDefault
headersNoOptional HTTP headers for authentication (raw server_url mode only)
team_idNoDuvo team UUID to operate on. API keys are pinned to a single team — omit this (it falls back to the key's team) or pass that same team; a different team is rejected. OAuth callers, who can span multiple teams, should pass the target team here.
server_urlNoRaw MCP server URL to probe (for custom MCP servers)
integration_slugNoCatalog integration slug. The backend resolves the MCP server URL and dummy auth headers server-side — no server_url or headers needed.

  5. First observed

TDQS

A3.7/5.0
Behavior2/5

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

The description does add real context beyond the annotations — it verifies reachability, checks that auth headers are correct, and returns the tool catalog. However, the claim 'Performs no writes' conflicts with readOnlyHint=false, an annotation explicitly stating the tool is not read-only; the agent receives two opposing signals about the tool's mutating side effects.

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

Conciseness4/5

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

Three front-loaded sentences with the core purpose first and no filler. The trailing parenthetical about the internal REST path is informative for routing but is internal plumbing an agent doesn't strictly need, which keeps it from a 5.

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?

With 100% schema coverage but no output schema, the description adequately states what is returned ('surfaces the tool catalog') and the dry-run intent. It omits failure behavior (unreachable URL, bad headers) and any rate/network-egress caveats, which would matter for an open-world network tool.

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

Parameters3/5

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

Schema description coverage is 100%, so the schema already documents team_id pinning, the headers/raw-URL mode, and the integration_slug enum. The description only echoes 'authentication headers (if any)' and 'URL', adding no syntax or mode-selection detail beyond what the schema provides — the baseline 3 for high-coverage schemas.

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 + resource + outcome: 'Probe an MCP server URL and list the tools it exposes.' The agent knows exactly what comes back (a tool catalog). It also distinguishes itself from the neighboring OAuth-check endpoint, so it is routable against siblings like checkMcpOAuth and createConnection.

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

Usage Guidelines4/5

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

'Useful as a dry-run before creating a connection' gives a clear when-to-use context and the description explicitly contrasts it with the OAuth probe. It falls short of 5 only because it points at a REST path (/v2/teams/.../oauth/mcp/check) rather than naming the sibling MCP tool (checkMcpOAuth) an agent would actually call.

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