list_provider_tools

Lists every tool a client's provider account exposes, including name, description, argument schema, and read-only status. Filter by keyword or schema to find the right tool before invoking it.

Instructions

What this client's account with this provider can actually be asked to do.

Every provider here runs its own MCP server with its own tools, and this returns them: the name, what it does, its argument schema, and whether the provider marks it read-only. Pair it with call_provider_tool, which invokes one.

This is how you do work Munim has no verb for. There is no per-operation tool to look for, because modelling one provider's tools as another tool's parameters is a losing game: Cloudflare's execute takes JavaScript. Read this list, then call what it names.

read_only is what the provider says about its own tool, and null means it said nothing. It is reported, not enforced; naming a client is what unlocks writing (D5).

names_only returns the name and read_only and nothing else, which for Resend is 2KB against 122KB. Use it first: the full listing has exceeded a caller's response limit outright. matching filters on the name, the description and the argument schema, so "which tools take a teamId" is answerable, which it is not by name and description alone.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
clientYesThe client to act on, by the name you registered them under. A write resolves this one client's credentials and no other.
matchingNoOnly tools whose name, description or argument schema contains this. Searching the schema is how you find every tool that takes a teamId.
providerYesThe provider to use, for example cloudflare, vercel or resend. Only what this client is actually connected to is reachable.
names_onlyNoReturn names and read-only flags only. Resend publishes 121KB of schemas and 2KB of names.

TDQS

A4/5.0
Behavior4/5

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

With no annotations, the description takes on the full burden. It explains that read_only is reported but not enforced, describes what is returned, and warns about response size limits for large providers. It does not explicitly say 'no side effects', but the listing nature is strongly implied by the content.

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

Conciseness2/5

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

The description is rambling and includes irrelevant, confusing asides such as 'This is how you do work Munim has no verb for' and 'naming a client is what unlocks writing (D5)'. Useful information is buried under opaque prose, making the description much longer than necessary.

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?

The description covers the essential context: how to use names_only, matching, the relationship to call_provider_tool, and the read_only semantics. It lacks a concrete example of the output shape, but since there is no output schema and the return content is described, it is mostly complete. The cryptic references slightly reduce completeness.

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

Parameters5/5

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

The schema already covers 100% of the parameters with descriptions, and the tool description adds meaningful extra semantics: matching searches names, descriptions, and argument schemas; names_only is for reducing payload size; client resolves a specific credential set; provider limits reachability. These additions go well beyond the baseline schema coverage.

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

Purpose4/5

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

The description clearly states that the tool returns the tools a client can use with a given provider, including names, descriptions, argument schemas, and read-only flags. It also distinguishes itself from call_provider_tool, which is invoked after listing. However, the meaning is obscured by odd digressions like 'Munim has no verb for' and references to 'D5', so it is not perfectly crisp.

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?

It gives concrete usage guidance: pair with call_provider_tool, use names_only first when response size is a concern, and use matching to search across schemas. It does not explicitly contrast with sibling tools like list_clients or find_across_clients, but the intended context is clear enough.

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