Scored across 50 tools
Most tools have clearly distinct purposes, with only minor overlaps like search_contacts (saved contacts) vs. search_people (prospecting database) and list_custom_fields_deprecated vs. list_fields. Descriptions effectively resolve ambiguity.
All tools follow a consistent verb_noun pattern in lowercase with underscores (e.g., create_contact, search_people). No mixed conventions or confusing name styles.
With 50 tools, the server is significantly oversized compared to typical MCP servers (3-15). While each tool serves a specific function, the sheer number makes it heavy for an agent to navigate, and many tools (e.g., search_phone_calls, search_activities) add complexity.
The tool surface covers most CRM and enrichment operations comprehensively (CRUD for contacts, opportunities, tasks, notes, labels; enrichment; search; sequences). Minor gaps exist: missing delete_account and delete_opportunity, and no get_sequence by ID, but these are not critical.
Model Context Protocol server for the Apideck Unified API. Connect any MCP-compatible agent framework to 100+ accounting systems, HRIS platforms, file storage providers, and more through one integration. More information https://www.apideck.com/mcp-server
Your agent needs B2B contacts and the pipeline objects around them — find the company, find the person, get the email, then write it back where your team works. **What you can ask for** • "Find heads of engineering at Series-B SaaS companies in the Nordics, with emails." • "Enrich these companies with headcount, industry and funding." • "What roles is this company hiring for right now?" • "Create an account and a contact, then log this opportunity." • "Search our sequences for messages sent to this domain." **How to use it** Point any MCP client at https://mcp.aisa.one/apollo/mcp and sign in with OAuth — there is no key to create or paste. 54 tools: people and organisation search and enrichment, job postings, accounts, contacts, opportunities and their stages, custom fields, labels, notes, users, email accounts, sequence messages and phone-call search — reads and writes. **Why this rather than the source** The full object model, not just a search endpoint, so an agent can finish the job rather than hand you a CSV. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Find the person here, then ask the same agent what their company's traffic looks like or what they rank for — without adding a second server. **What it costs** Finding and inspecting an operation is free. Running one is billed per call at API prices, with no seat and no monthly minimum, and every call takes max_price_usd so an agent cannot overspend by accident. **Where else it reaches** https://mcp.aisa.one/sales/mcp adds Similarweb and creator discovery around it.
