Search or page through organization contacts, up to 50 per page. Returns nextCursor for another page when available.
| Name | Required | Description | Default |
|---|---|---|---|
| org | No | Organization slug. Only needed when you belong to multiple organizations; must be one returned by list_my_orgs. | |
| cursor | No | Opaque cursor returned by the previous page. | |
| search | No | Optional contact search text. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds the page-size limit (50 per page) and the nextCursor return behavior, which are useful behavioral details. It doesn't mention whether search matches name/email/fields, but that's a minor gap given the 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?
One concise sentence with no wasted words. It front-loads the main function and includes the most important operational detail (pagination limit and cursor).
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?
For a read-only search/pagination tool with no output schema and full parameter documentation, the description covers the essential usage: searching, paging, and the cursor mechanism. It could note what fields are searchable or that results are sorted, but it is otherwise complete for an agent to call it correctly.
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 description coverage is 100%, so the schema fully documents all three parameters: org, cursor, and search. The description reinforces the cursor's role ('Returns nextCursor for another page') but doesn't add new meaning beyond the schema. Baseline 3 is appropriate.
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's function: search or page through organization contacts, with a specific pagination limit (50 per page). It distinguishes itself from related contact tools like get_contact, list_associated_contacts, and update_contact by focusing on searching/paging through all org contacts.
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?
The description conveys when to use it: when you need to search or page through contacts. It mentions the nextCursor pagination mechanism, which implies iterative use. It doesn't explicitly name alternatives or when-not-to-use, but the function is clear enough against siblings like get_contact or list_associated_contacts.
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.
Most tools use distinct resource+action patterns and descriptions actively disambiguate similar cases, but several pairs remain easy to confuse: search vs semantic_search, send_email vs send_speaker_message, and the cluster around submission handling (decide_submission, set_submission_status, update_form_pipeline). The descriptions help, but the overlap is more than a single edge case.
The set overwhelmingly follows verb_noun snake_case (create_session, update_sponsor, list_events) and prefixes are applied predictably. Minor deviations like semantic_search, bare search, check_in_attendee, and list_tracks_rooms break the pattern slightly, but they are still readable and not chaotic.
55 tools is an extreme surface for an MCP server, even for a broad event-management platform, and it exceeds the 50+ threshold for severe over-scoping. Many tools are micro-variants of the same domain—multiple send_* tools and several submission-status tools—creating high selection burden for an agent.
The server covers a wide range of event, CRM, session, sponsor, form, and email workflows, but there are notable lifecycle gaps: events can be created and read but not updated or deleted, email templates have no update/delete path, and full form submission details and approval actions are absent. These are significant but not catastrophic because much of the core scheduling and contact workflow is covered.
