Cursor uses the same mcpServers schema as Claude Desktop. Project config wins over global.

Use Cases

Real-world ways to use mcp-server-mas-sequential-thinking

Stress-test a strategic decision with six perspectives

👤 Founders, PMs facing non-obvious tradeoffs ⏱ ~15 min intermediate

When to use: You're debating something hard ('raise now or bootstrap?', 'kill the feature?') and want sharper internal debate than single-agent brainstorming.

Prerequisites

LLM API key (DeepSeek recommended for cost) — platform.deepseek.com

Flow

Frame the question

sequentialthinking: Should we raise a Series A now at $20M post to extend runway 24 months, or bootstrap further and raise at a likely higher valuation in 12 months? Here's our context: [facts]✓ Copied

→ Six-agent analysis + synthesis recommendation
Interrogate the synthesis

The synthesis recommends X. What's the weakest point in that reasoning? Have the critical agent push harder.✓ Copied

→ Sharper critique

Outcome: A well-rounded, written-down analysis you can share with co-founders.

Pitfalls

Token cost explosion on long context — Keep the framing tight — 200-500 words of context; agents multiply it 6x
Synthesis can average to mush — Pass the recommendation back through with decide between options A and B, don't hedge

Have the critical and emotional agents red-team your plan

👤 Anyone shipping a risky plan ⏱ ~10 min beginner

When to use: You drafted a launch plan and want the critical + emotional agents specifically to pressure-test it.

Flow

Submit the plan

sequentialthinking with focus on critical + emotional: Here's my launch plan [paste]. Find the three biggest risks and the three emotional reactions customers will have.✓ Copied

→ Two-perspective analysis

Outcome: Risks you hadn't noticed; emotional reactions to prepare for.

Pitfalls

Using this for simple yes/no questions wastes tokens — Reserve for multi-faceted decisions; use regular Claude for simple ones

Brainstorm with the creative agent grounded in real web data

👤 Content strategists, product people ⏱ ~15 min intermediate

When to use: You need ideas that aren't just from the model's training data — agents should search the web for current angles.

Prerequisites

Exa API key — exa.ai — separate subscription

Flow

Enable Exa

Set EXA_API_KEY in env. Run sequentialthinking on: 'novel marketing angles for a local bakery in 2026'. Let creative + factual agents search the web.✓ Copied

→ Grounded ideas with citations

Outcome: Current, defensible creative angles.

Pitfalls

Exa search cost on top of LLM cost — Cap agent search budget via Exa rate limits

Combinations

Pair with other MCPs for X10 leverage

server-mas-sequential-thinking + notion

Save the six-agent analysis as a decision doc

Run sequentialthinking on this strategic question, then create a Notion page in 'Decision Log' with all agent outputs and the synthesis.✓ Copied

Tools

What this MCP exposes

Tool	Inputs	When to call	Cost
sequentialthinking	prompt: str, perspectives?: str[], model?: str	Multi-faceted questions that benefit from different cognitive modes	5-10x single-agent tokens

Cost & Limits

What this costs to run

API quota: Bounded by your LLM provider quota
Tokens per call: 5-10x a single-agent call — easily 20k-80k tokens per invocation
Monetary: DeepSeek is cheap (~$0.14/M input); with Anthropic Opus expect $1-3 per invocation
Tip: Default to DeepSeek; only use Opus for the synthesis step via dual-model config.

Security

Permissions, secrets, blast radius

Credential storage: LLM_PROVIDER_API_KEY + optional EXA_API_KEY in env vars

Data egress: Your prompts go to 6 agents' worth of LLM calls + optional Exa searches

High token usage — set daily spend caps with your LLM provider.
Not suitable for latency-sensitive contexts; each call is tens of seconds.

Troubleshooting

Common errors and fixes

Very slow / timeout

6 agents running sequentially = 30-60s. Increase client timeout to 120s+.

OPENAI_API_KEY / DEEPSEEK_API_KEY not found

Set the env var matching your chosen provider. Config file selects the provider.

Output inconsistent between runs

Stochastic by design — lower temperature or fix seed if your LLM supports it.

Alternatives

mcp-server-mas-sequential-thinking vs others

Alternative	When to use it instead	Tradeoff
Native sequential-thinking MCP (official)	You want single-agent chain-of-thought without the multi-agent cost	Simpler, faster, cheaper; less diverse output
Direct use of Agno framework	You want to customize the agent roles	Not an MCP; code-first
