Galaxy Brain
Think. Do. Done.
Sequential Thinking + Sequential Doing = Complete Cognitive Loop
What is this?
Galaxy Brain is an MCP server that combines two powerful concepts:
- Sequential Thinking (from Anthropic's MCP) - structured reasoning with revision and branching
- Sequential Doing (from the basement) - batch execution with variable piping between operations
Together they form a complete cognitive loop: think through a problem, convert thoughts to actions, execute, done.

Installation
Quick Install (PowerShell)
git clone https://github.com/basement-revolution/galaxy-brain.git
cd galaxy-brain
.\scripts\install.ps1
Quick Install (Bash)
git clone https://github.com/basement-revolution/galaxy-brain.git
cd galaxy-brain
chmod +x scripts/install.sh
./scripts/install.sh
Manual Install
pip install galaxy-brain
Then add to your Claude Desktop config (%APPDATA%\Claude\claude_desktop_config.json on Windows):
{
"mcpServers": {
"galaxy-brain": {
"command": "python",
"args": ["-m", "galaxy_brain.server"]
}
}
}
Usage
The Galaxy Brain Move: think_and_do
One tool to rule them all:
think_and_do({
"problem": "I need to read a config file, parse it, and count the keys",
"thoughts": [
"First I need to read the config file",
"Then parse it as JSON",
"Finally count the number of keys"
],
"operations": [
{
"service": "file",
"method": "read",
"params": { "path": "config.json" }
},
{
"service": "transform",
"method": "json_parse",
"params": { "content": "$results[0].result.content" }
},
{
"service": "python",
"method": "eval",
"params": { "expression": "len($results[1].result)" }
}
]
})
See that $results[0].result.content? That's variable piping - each operation can reference results from previous operations.
Thinking Tools
Start a thinking session and reason step by step:
# Start thinking
start_thinking({
"problem": "How should I refactor this authentication system?",
"initial_estimate": 5
})
# Returns: { "session_id": "think_abc123..." }
# Add thoughts
think({
"session_id": "think_abc123...",
"thought": "The current system uses session cookies...",
"confidence": 0.8
})
# Realize you were wrong? Revise!
revise({
"session_id": "think_abc123...",
"revises_thought": 2,
"revised_content": "Actually, we should use JWTs because...",
"reason": "Stateless is better for our scale"
})
# Want to explore an alternative? Branch!
branch({
"session_id": "think_abc123...",
"branch_from": 3,
"branch_name": "oauth_approach",
"first_thought": "What if we used OAuth2 instead?"
})
# Done thinking
conclude({
"session_id": "think_abc123...",
"conclusion": "We should migrate to JWT with refresh tokens",
"confidence": 0.9
})
Doing Tools
Execute operations with variable piping:
execute_batch({
"batch_name": "process_data",
"operations": [
{
"service": "shell",
"method": "run",
"params": { "command": "curl -s https://api.example.com/data" }
},
{
"service": "transform",
"method": "json_parse",
"params": { "content": "$results[0].result.stdout" }
},
{
"service": "file",
"method": "write",
"params": {
"path": "output.json",
"content": "$results[1].result"
}
}
]
})
Available Services
| Service | Methods | Description |
|---|---|---|
python | execute, eval | Run Python code or evaluate expressions |
shell | run | Execute shell commands |
file | read, write, exists | File operations |
transform | json_parse, json_stringify, extract, template | Data transformations |
Bridge Tools
Convert thinking sessions to action plans:
# Generate plan from concluded session
generate_plan({
"session_id": "think_abc123..."
})
# Execute the generated plan
execute_plan({
"plan_id": "plan_xyz789..."
})
Variable Piping Syntax
Reference previous results using $results[N].path.to.value:
$results[0] # Full result of operation 0
$results[0].result # The result field
$results[0].result.content # Nested access
$results[1].result.data[0] # Array access (in path format)
Variables are resolved before each operation executes, so you can build pipelines:
operations = [
# Op 0: Read a file
{ "service": "file", "method": "read", "params": { "path": "input.txt" } },
# Op 1: Use content from op 0
{ "service": "python", "method": "execute",
"params": { "code": "print(len('$results[0].result.content'))" } },
# Op 2: Use stdout from op 1
{ "service": "file", "method": "write",
"params": { "path": "count.txt", "content": "$results[1].result.stdout" } }
]
Configuration
Create galaxy-brain.json in your working directory:
{
"thinking": {
"max_thoughts": 50,
"max_branches": 10,
"max_revisions_per_thought": 5
},
"doing": {
"max_operations": 50,
"default_timeout": 30,
"max_timeout": 300,
"stop_on_error": true
},
"bridge": {
"auto_execute": false,
"validate_before_execute": true
},
"log_level": "INFO"
}
Or use environment variables:
GALAXY_BRAIN_LOG_LEVELGALAXY_BRAIN_MAX_THOUGHTSGALAXY_BRAIN_MAX_OPERATIONS
Why "Galaxy Brain"?
Because when you combine structured thinking with chained execution, you're operating on a whole other level.
Think. Do. Done. Big brain energy. Cosmic efficiency.
