Schema Quality & AI Usability69
- AI-judged instruction clarity (good).Pass

- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management67
- Stability observed for 20 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage67
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 0% of tool parameters carry a description.Fail
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 2 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the Pulse MCP server?
Pulse runs locally as an npm package, launched with npx -y @pulse-circle/mcp. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
pulse_connect ~79
Use when the user wants subscription revenue, MRR, LTV, trials or refunds in Pulse, or asks how to connect RevenueCat, the Apple App Store or Google Play. Returns the setup steps for that source: which keys to create and where to paste them. Read-only: returns documentation, connects nothing itself.
| Name | Type | Req | Description |
|---|---|---|---|
| source | string | yes | – |
No output schema declared.
No examples provided.
pulse_setup_guide ~86
Use when the user wants to add Pulse product analytics or event tracking to an app, or asks how to install the Pulse SDK. Returns the install command and code snippet for web, react-native, swift (iOS) or kotlin (Android) — apply it to the codebase yourself. Read-only: returns documentation, reads no account data.
