MCP.AI for IDE agents (Cursor, etc.): log in in the browser, copy the access token. Best: add it to this server's config as a header Authorization: Bearer <token> for a permanent, non-expiring connection. Or paste it here for a session-only login: call with { token: "" } after the user pastes, or with no args to get the link.

Changes observed during successful MCP inspections. Dates show when Glama detected each change.
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate idempotent, non-destructive. Description adds workflows for token vs no-args, explaining behavior beyond annotations. Consistent 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.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences, efficient, front-loaded with target audience. Every sentence adds value.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Covers main use cases well. No output schema; return value for success not detailed, but sufficient for an auth tool. Complete given complexity.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 0% coverage; description compensates by explaining the 'token' parameter is a JWT for session login, and how to obtain it. Adds significant meaning.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool handles authentication, providing a browser login link or accepting a token. It distinguishes itself from sibling tools like 'connect' by being specifically for authentication.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly describes two usage modes: session-only token paste or permanent config-based login, advising best practice. No negatives but clear context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Almost all tools have clear purposes, especially with the contasimples_ prefix. Some overlap between statement and summary, but descriptions differentiate well. The general tools (marketplace, report_bug, etc.) are completely different from the financial ones, which reduces potential confusion.
The domain tools follow a consistent verb_noun pattern (e.g., contasimples_card_write_block). However, the inclusion of general tools like authenticate, connect, marketplace breaks the pattern. This inconsistency lowers the score.
With 24 tools covering authentication, financial operations, and platform utilities, the number is reasonable for a moderately complex MCP server. It doesn't feel excessive or too thin.
The toolset covers key financial operations (balance, bills, cards, statements, summary) and some mutations (block/unblock, create invite, delete user). However, missing CRUD for several entities (e.g., no update user, no create card, no delete invite) leaves gaps. The presence of platform utilities adds breadth but not depth.
