marketplace

The official mcp.ai marketplace — the in-platform catalog of every MCP/tool, AND the way to run them. Covers capability requests like "find an MCP that does X", "consulta um CPF", "is there a tool for Y". Core flow: action=search discovers MCPs by intent → describe returns one MCP's full profile (every tool with its id + params, pricing, auth) so you pick the right tool_id → invoke RUNS that tool. KEY: invoke works even when the MCP is NOT installed — it runs the tool pontualmente (one-off), without adding the MCP to the toolkit and without bloating the tool list. If the MCP needs a credential/login, invoke returns a connect link; if it is paid and the wallet is empty, invoke returns a checkout/top-up link (the user opens it, then you retry). Use install only to make an MCP PERMANENT in the active toolkit (its tools then show up natively in future sessions); prefer invoke for a single/occasional use. list_tools lists what is callable right now. subscribe/cancel handle per-MCP billing; report_bug sends feedback; request_mcp asks us to build a NEW MCP when nothing fits. Search/describe flag installed_in_toolkit vs installed_in_workspace. Writes (install/uninstall/subscribe/cancel and the one-off install behind invoke) require workspace owner/admin. It also carries the mcp.ai PROMPT LIBRARY, which is about ready-made prompt TEXT rather than MCPs: search_prompts finds one, get_prompt returns its full text with {{variables}} filled, and publish_prompt saves a prompt and returns a shareable mcp.ai/p/ link that opens without login.

TDQS

A4.3/5.0
Behavior5/5

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

The description goes well beyond the annotations (readOnlyHint=false, openWorldHint=true), detailing one-off invocation behavior without installation, credential/connect links, checkout/top-up flows, permission requirements for writes (workspace owner/admin), and the prompt library behavior. No contradiction with annotations.

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?

The description is a single dense paragraph but well-organized: core flow, then invoke vs. install, then billing/feedback, then prompt library. It front-loads key points and highlights the 'KEY' invoke behavior. Some sentences are long and could be split, but the structure is logical.

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?

Despite no output schema, the description covers major return behaviors (profile with tool_id/params/pricing/auth, connect/checkout links, prompt full text). It does not spell out every return value for every action, but for a 23-param, multi-action tool it is fairly complete.

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 0%, and the description compensates by explaining the core parameters and flow: action=search, describe returns profile with tool_id, invoke takes tool_id and arguments. However, many parameters (prompt_title, cancel_reason, request_details, etc.) remain unexplained, leaving the 23-param schema to carry the burden. The enums for action and cancel_reason are self-documenting.

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?

The description clearly defines the tool as the mcp.ai marketplace — the in-platform catalog and the way to run MCPs. It enumerates specific actions (search, describe, invoke, install, etc.) and distinguishes itself from domain-specific sibling tools like openfinance and authenticate by describing the marketplace as the platform-wide catalog and runner.

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?

The description provides explicit guidance on when to use invoke vs. install: prefer invoke for one-off/occasional use, use install to make an MCP permanent. It also directs request_mcp when nothing fits, and distinguishes list_tools as listing currently callable tools. It does not explicitly name sibling tools as alternatives, but the high-level role is clear.

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

A4.1/5.0
Disambiguation4/5

Tools are mostly distinct, with clear descriptions differentiating them. Some overlap between openfinance_list_accounts and openfinance_get_accounts_detail, but descriptions clarify that one returns summaries and the other full details. The marketplace tool is very detailed and avoids confusion with Open Finance tools.

Naming Consistency3/5

The Open Finance tools follow a consistent openfinance_verb_noun pattern, but other tools (authenticate, connect, marketplace, report_bug, show_version, toolkit_info) do not use a prefix. This mix of conventions reduces overall consistency, though within the Open Finance subset the pattern is clear.

Tool Count4/5

24 tools is a reasonable count for a platform covering authentication, marketplace, and detailed Open Finance operations. The number is slightly high but each tool has a clear purpose and none seem redundant.

Completeness5/5

The tool set covers the full lifecycle of bank connections: listing accounts, transactions, credit card bills, investments, loans, force syncing, provider status, and category management. The marketplace tool also allows extending functionality. No obvious gaps for the intended financial data domain.
