Callsphere MCP Server 工具

5

Search CallSphere's published articles on voice AI, MCP, Claude, agentic AI, Twilio/WebRTC, and how-to guides. Returns up to N matching posts with title, description, slug, date, and tags. Use this first to discover relevant content, then call `read_doc` with a slug for the full body.

Fetch the full text of a single CallSphere blog post by its slug (e.g. from search_voice_ai_docs results). Returns the title, metadata, and full markdown/HTML body.

Compute a CallSphere ROI estimate for a business: monthly + annual savings, after-hours revenue recovery, recommended plan, and payback period. Industry-aware defaults are applied when optional inputs are omitted. Useful for business owners evaluating CallSphere's AI agent platform — voice agents (the flagship front door) plus chat agents, both of which automate your business workflows.

Return a narrative case study for one of CallSphere's 6 live industries: problem, solution, measurable results, customer quote. Use when a user asks 'who else has done this?' or wants social proof.

Look up canonical CallSphere facts: pricing tiers, supported industries, founder contact, integrations, compliance posture, supported languages, or demo links. Use 'all' to get a full overview.

概览

What is Callsphere?

Callsphere is a public, read-only Model Context Protocol (MCP) server that gives any AI assistant – including Claude, Cursor, Cline, Continue, Windsurf, Zed, or ChatGPT via JSON-RPC – direct access to CallSphere’s voice‑AI knowledge base, industry ROI calculator, case studies for six verticals, and product facts.

How to use Callsphere?

Connect to https://callsphere.ai/api/mcp using Streamable HTTP transport. Install with claude mcp add --transport http callsphere https://callsphere.ai/api/mcp (Claude Code) or add it to your client’s MCP config (Claude Desktop, Cursor, Cline/Continue/Windsurf). For clients without MCP support, send plain JSON‑RPC 2.0 POST requests to the same endpoint.

Key features of Callsphere

  • Full‑text search across 500+ voice‑AI articles
  • Industry‑aware ROI calculator with transparent assumptions
  • Case studies for 6 verticals (dental, healthcare, HVAC, real estate, salon, law)
  • Canonical product info: pricing, integrations, compliance, languages
  • No authentication required – free and public (read‑only)
  • Rate limited to 120 requests per minute per IP

Use cases of Callsphere

  • Search for articles on building MCP servers with Twilio
  • Calculate voice‑AI ROI for a dental practice or other vertical
  • Retrieve a case study for HVAC after‑hours dispatch
  • Compare pricing tiers and check HIPAA readiness
  • Look up supported languages and compliance posture
