What to fix (8)

Loading this server's tool list costs an agent ~62,021 tokens before any work — more than 99% of MCP servers.

Split rarely-used tools into a separate server or a toolset the client can enable, or expose one "search tools" entry point. Many agents load every connected server's tools into every request. How to fix →

2 tool definition(s) exceed ~1,200 tokens each (largest: creative_save_draft, ~20,914).

Move long reference material out of descriptions (link a doc or expose a resource), drop repeated examples, and collapse large enums. Trimming these to ~600 tokens saves ~21,027 tokens every session. How to fix →

Tools: creative_save_draft, call_creative_agent_preset · saves ~21,027 tokens/session

118 tools on one server. Tool-selection accuracy drops as the menu grows, and some clients (e.g. Cursor) cap the number of active tools.

Group tools by task into smaller servers or toolsets, and merge near-duplicates behind one tool with a mode parameter. How to fix →

2 parameter(s) across 1 tool(s) have no description.

Add a "description" to each parameter with its format and an example ("ISO 8601 date, e.g. 2026-10-17"). This is the commonest cause of wrong arguments on the first call. How to fix →

Tools: creative_save_draft

1 tool(s) look like they change state (create/send/delete/pay…) but declare no destructiveHint.

Set annotations {"readOnlyHint": false, "destructiveHint": true|false, "idempotentHint": …}. Clients use these to ask the user before a side effect and to auto-approve safe reads. How to fix →

Tools: fleet_create_issue

Handshake + tools/list takes ~3,199 ms.

Serve tools/list from memory, keep the process warm, and host close to your users. Every new agent session pays this before its first call.

12 tools share an identical description with another tool on this server.

Make each description say how the tool differs from its siblings, or the model will pick between them at random. How to fix →

Tools: dispatch_desk_researcher, dispatch_desk_researcher_async, dispatch_market_analyst, dispatch_market_analyst_async, dispatch_qualitative_researcher and 7 more

Requires authentication; tool definitions could not be read anonymously.

If discovery should be public, allow initialize + tools/list without credentials and gate only tools/call. Directories and routers can then list your tools.

FAQ

Is the Heista MCP server down right now?

How many tools does Heista MCP server provide?

Heista MCP server advertises 118 tools, including add_brand_asset, adformula_intelligence, call_creative_agent_preset, call_creative_worlds, chat_with_creative_worlds.

How do I install Heista MCP server?

Point your MCP client at this streamable-http endpoint: https://www.heista.co/api/mcp/mcp

Is the Heista MCP server safe to connect to an AI agent?

Glimind scanned all 118 tool definitions for tool-poisoning patterns — hidden or invisible characters, instructions that override the model, concealment from the user, requests to read credential or MCP config files, conversation exfiltration and cross-tool shadowing — and found none. This checks what the server tells the model, not what its code does; review the source before granting access to sensitive data.
