CatchAll integrates with Claude through two paths:
- MCP server: Connects CatchAll as a tool in Claude’s chat interface. Claude
calls pre-built tools to submit jobs, poll status, and pull results — no code
execution required.
- Python agent: Uses the Anthropic SDK to run CatchAll queries
programmatically in an agentic loop.
You can also use the
CatchAll API SKILL alongside either path
to improve query quality and result presentation.
Before you start
Connect MCP server
The MCP server authenticates with the CatchAll API and exposes tools in Claude.
Claude.ai
Claude Desktop
Claude Code
Configure connection
Fill in the Add custom connector dialog:
- Name:
CatchAll
- Remote MCP server URL:
https://catchall-mc.fastmcp.app/mcp?apiKey=YOUR_CATCHALL_API_KEY
Add and verify
Click Add. Verify that CatchAll appears under Web in your connectors list.
Test connection
Open a new chat and type a CatchAll query, for example: “Find AI company acquisitions in the last 7 days, limit 5”. Claude should call the CatchAll tools and return structured results.
Claude Desktop does not natively support remote MCP servers. Use mcp-remote to proxy the connection.Install mcp-remote
npm install -g mcp-remote
Open configuration file
Open your Claude Desktop configuration file:
- macOS:
~/Library/Application Support/Claude/claude_desktop_config.json
- Windows:
%APPDATA%\Claude\claude_desktop_config.json
Add CatchAll entry
Add the following to your configuration file:{
"mcpServers": {
"catchall": {
"command": "npx",
"args": [
"-y",
"mcp-remote",
"https://catchall-mc.fastmcp.app/mcp?apiKey=YOUR_CATCHALL_API_KEY"
]
}
}
}
Restart Claude Desktop
Quit and relaunch Claude Desktop, as it loads MCP tools on startup.
claude mcp add --transport http catchall \
"https://catchall-mc.fastmcp.app/mcp?apiKey=YOUR_CATCHALL_API_KEY"
The MCP URL contains your API key. Treat it as a secret and do not share it or
commit it to version control.
The MCP server exposes tools for jobs (initialize, submit, poll, pull results,
continue) and monitors (create, update, list, enable, disable, pull results).
For the full tool reference, see
MCP server > Available tools.
Python agent
To use CatchAll programmatically with Claude, use the Anthropic SDK to execute
CatchAll API calls in an agentic loop.
Setup
pip install -r requirements.txt
Set environment variables:
export CATCHALL_API_KEY=YOUR_CATCHALL_API_KEY
export ANTHROPIC_API_KEY=YOUR_ANTHROPIC_API_KEY
Basic agent example
The agent uses hardcoded tool definitions and a standard agentic loop: submit,
wait, pull with polling.
client = anthropic.Anthropic(api_key=os.environ["ANTHROPIC_API_KEY"])
response = client.messages.create(
model="claude-sonnet-4-20250514",
max_tokens=4096,
tools=TOOLS, # Hardcoded tool definitions in claude_agent_example.py
messages=[
{"role": "user", "content": "Find pharma M&A deals in the last 7 days, limit 20"}
]
)
For the complete implementation, including polling and result handling, see the
agent example on GitHub.
