VoiceForge - Autonomous Voice AI Agents, Real-Time Speech Pipelines & Telephony Engine MCP

https://server.smithery.ai/tofan96you/voiceforge-mcp/mcp

● healthy

Universal voice AI engine for Cursor, Claude Code & Windsurf. Architects complete voice agent blueprints (OpenAI Realtime vs Pipecat vs LiveKit matrix, sub-800ms latency budgets), generates production speech pipelines (Pipecat bots with barge-in, Twilio Media Streams bridges, WebRTC clients), designs human-feeling conversation flows (voice-optimized prompts, error recovery ladders, data capture), optimizes voice-to-voice latency with streaming fixes, and deploys to phone numbers with compliance checklists and unit economics.

MCP readiness

B · 83/100

Readiness is how fully this listing follows its protocol and how it behaved in our probes over 30 days. It is shown for reference and does not move it in search. Search order and leaderboards use the separate quality grade (here C+, 70.0/100), which weighs availability, conformance, p95 speed and descriptor. How the two differ

Valid MCP handshake	10/10	initialize and tools/list both answered.
Live MCP endpoint	24/25	Endpoint answers the MCP initialize handshake (4963 ms); slow response -1.
Protocol revision	5/10	Speaks MCP 2024-11-05, 4 revision(s) behind 2026-07-28.
Signed descriptor	n/a	No MCP standard defines a signed server descriptor.
Uptime (30 days)	15/15	30/30 probes succeeded over 30 days (100%).
Tool declaration	10/10	Lists 5 tool(s) with descriptions.
Verified identity	5/10	Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Freshness + modern flags	4/5	seen in a source within 7 days.
Auth declaration	2/5	Declares credential scheme: smithery_api_key.

Applicable criteria total 90 points, scaled to 100.

Responsiveness: Slow (4963 ms; bands ≤2.5 s, ≤5 s, ≤8 s, slower; penalty only).

Measured 2026-11-11.

Nine criteria, the same as the A2A readiness score, read from our daily MCP probe (initialize + tools/list) and 30-day probe history. No MCP standard defines a signed server descriptor, so that criterion is n/a and the other 90 points are scaled to 100. Grades: A>=90, B>=75, C>=60, D>=40, F<40. Display only: search order uses the quality grade.

Compared with peers

Against 53,039 reachable MCP servers in our daily snapshot (2026-11-12 06:46 UTC). Display only; it does not change search order.

Readiness: Higher than 60% of peers; This listing 83 · peer median 81
Latency: Faster than 29% of peers; This listing 513 ms · peer median 326 ms

Where it loses the most points, and how to win them back

Protocol revision −5 — Support the current protocol revision.
Now: Speaks MCP 2024-11-05, 4 revision(s) behind 2026-07-28.
Verified identity −5 — Claim the listing and prove control of its domain.
Now: Publisher declared (repository, package or homepage); claim this listing to verify domain control.
Auth declaration −3 — State how to authenticate (an auth scheme, or that none is needed).
Now: Declares credential scheme: smithery_api_key.
