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.

  4. First observed

TDQS

A4.2/5.0
Behavior5/5

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

Discloses important behaviors beyond annotations: invoke runs tools one-off even when not installed, returns connect/checkout links for auth/payment, writes require owner/admin, and install makes MCPs permanent. No contradiction with annotations (readOnlyHint=false, destructiveHint=false).

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 a very long single paragraph; although dense with useful information, it lacks structure (bullets/headings) and would benefit from front-loading the core flow. It feels overlong relative to typical descriptions.

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?

Given the tool's complexity, the description covers workflow, auth, billing, permission, and prompt-library behaviors thoroughly, and mentions edge cases like missing credentials and empty wallet. However, with no output schema, it doesn't describe return formats for search/describe/list_tools, and parameter-level details are incomplete, so a perfect completeness score isn't warranted.

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

Parameters2/5

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

The description explains the meaning of many action enum values and the core flow, but with 23 parameters and 0% schema coverage it does not document parameter syntax or formats (arguments JSON, immediate, tier_slug, prompt_* fields, etc.). This leaves significant ambiguity for correct invocation.

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 identifies marketplace as the mcp.ai catalog and execution layer for MCPs, with a concrete core flow (search → describe → invoke). It distinguishes itself from sibling tools (getnet_*, authenticate, toolkit_info) by naming its unique actions and the prompt library.

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

Usage Guidelines5/5

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

Explicit usage guidance: prefer invoke for single/occasional use, install only for permanent toolkit addition; request_mcp when nothing fits; list_tools for currently callable tools. It also states permission requirements for writes (owner/admin).

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

A3.6/5.0
Disambiguation5/5

Each tool has a clearly distinct function: Getnet-specific tools target different resources (cards, payments, customers, accounts), while platform tools handle authentication, connection status, marketplace lookup, bug reporting, and version info. There is no overlap in the actions they perform.

Naming Consistency2/5

The Getnet tools follow a consistent `getnet_` prefix with verb_noun structure, but the platform-level tools (authenticate, connect, marketplace, report_bug, show_version, toolkit_info) use a mix of bare verbs and noun phrases, and lack the prefix. This creates two divergent naming conventions within the same server.

Tool Count4/5

With 11 tools, the server has a reasonable number for a mixed-purpose integration. However, the inclusion of platform-wide management tools alongside Getnet-specific ones makes the scope feel broader than a typical payment server, but the count itself is not excessive.

Completeness2/5

The Getnet-specific tools are read-only (list/get operations) with no ability to create, update, or delete customers, cards, or payments. This is a significant gap for a payment-related server, though the marketplace tool could potentially compensate by invoking other MCPs.
