Disconnect a connected account

disconnect_connector
DestructiveIdempotent

Disconnect a third-party account from this workspace (Meta, Google Ads, Google Drive/Sheets/Docs, YouTube, TikTok, LinkedIn, X, Reddit, Pinterest, Google Business, Microsoft Advertising/OneDrive, Slack, …). This always drops the stored credentials, so every tool for that provider stops working immediately and posts/campaigns already published are NOT affected. WHETHER IT ALSO REVOKES THE GRANT AT THE PROVIDER DEPENDS ON THE PROVIDER — a few (Threads, Microsoft) publish no revocation endpoint, so the authorisation stays in place until the user removes it in that provider's own settings. The unconfirmed call reports which it is for this provider (list_connectors also carries it as revokesAtProvider) — relay that verbatim rather than promising a revoke. RECONNECTING NEEDS A BROWSER (the provider's consent screen) — an agent cannot undo this. Name the provider to the user, then call with confirm:true. Use list_connectors for the exact provider ids.

A4.6/5.0
Behavior5/5

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

The description goes far beyond the annotations, disclosing that credentials are always dropped, tools stop immediately, published posts are unaffected, revocation depends on provider, some providers lack revocation endpoints, and reconnecting requires a browser. This rich behavioral context helps the agent set user expectations and avoid promising actions it cannot complete.

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 long but every sentence contributes essential information—consequences, provider variability, and the undoing limitation. It is front-loaded with the main purpose and effects, and the structure flows logically from effect to caveat to action. While dense, it avoids redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite lacking an output schema, the description covers what the agent needs: the unconfirmed call reports revocation status, the exact provider ID source, and the confirm requirement. It also instructs the agent to relay info verbatim, ensuring correct usage. No critical operational detail is missing.

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

Parameters4/5

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

Schema coverage is 100%, so the baseline is 3, but the description adds meaningful detail: provider must match list_connectors exactly, and confirm must be true because reconnecting needs the user's browser. This clarifies the semantics beyond the schema's terse field descriptions.

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 explicitly states the action ('Disconnect a third-party account from this workspace') and enumerates the supported providers, distinguishing it clearly from siblings like leave_connector. The verb and resource are specific and unambiguous.

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 clear context on when to use the tool, including the prerequisite of calling list_connectors for provider IDs and the need for user confirmation. It does not explicitly exclude alternatives like leave_connector, but it names list_connectors as the supporting tool, which is sufficient guidance for selecting this tool.

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

A3.7/5.0
Disambiguation2/5

With 293 tools, the surface is enormous and many tools have overlapping purposes—multiple posting tools (post_to_meta, post_to_linkedin, schedule_post, etc.), multiple analytics tools per channel, and several search tools (search_meta_ads, search_instagram, search_reddit...). While each description is detailed, the volume makes it difficult for an agent to reliably distinguish between similar tools without careful reading, leading to frequent misselection.

Naming Consistency4/5

The naming is largely consistent with a verb_noun pattern (post_to_*, list_*, create_*, delete_*, update_*, manage_*). There are clear families for major operations. A few outliers like 'google_business_account', 'hermoso_capabilities', and 'store_get' break the pattern, but the overwhelming majority follow a predictable structure, making navigation somewhat easier.

Tool Count1/5

293 tools is far beyond any reasonable scope for a single MCP server, even for a comprehensive marketing platform. The calibration guide flags 50+ as an extreme mismatch, and this is nearly six times that threshold. Such a large surface overwhelms context windows, increases the probability of misselection, and makes it impractical for agents to learn or use effectively.

Completeness4/5

The tool set covers a vast domain: ad creation and rendering, posting across nine+ social channels, analytics and reporting, file management (Drive/OneDrive), competitor research, brand management, and more. It appears to provide CRUD and lifecycle coverage for most resources. While there may be minor gaps given the immense scope, the overall coverage is impressively comprehensive.
