A2A INTEGRATION · CUSTOM TOOL

Use GitDealFlow A2A with Aider

AI pair-programmer in your terminal. Terminal-first developer-investors who prefer git-aware agentic editing.

Crunchbase API: $20K/yr. GitDealFlow A2A: free, no signup.

Aider doesn't have native MCP, but its /run command + .aider.conf.yml command aliases make A2A trivial to wire. Drop a one-liner alias and any aider session can pull signals mid-edit ('aider, /signal trending fintech' returns the data inline so you can paste it into a doc the agent is editing).

Install

pip install aider-chat

Command alias in .aider.conf.yml

# .aider.conf.yml in your repo
# Then in aider: /signal trending
# Or: /signal sector ai-ml
shell-commands:
  signal: |
    curl -sS -X POST https://signals.gitdealflow.com/api/a2a \\
      -H 'Content-Type: application/json' \\
      -d '{"jsonrpc":"2.0","id":1,"method":"message/send","params":{"message":{"role":"user","parts":[{"kind":"text","text":"'$1'"}]}}}' \\
      | jq -r '.result.artifacts[1].parts[0].text // .result.artifacts[0].parts[0].text'

Inline /run with curl

# In any aider session:
# /run curl -X POST https://signals.gitdealflow.com/api/a2a -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","id":1,"method":"message/send","params":{"message":{"role":"user","parts":[{"kind":"text","text":"trending"}]}}}'

# Aider includes the output in its context, so the next prompt
# can reference the returned startups by name.

What you can ask

/signal trending — top 20 of the week, plaintext.
/signal sector fintech — sector watchlist.
/signal startup Roboflow — single-startup profile.
/signal methodology — full methodology text for citing in a doc.

Gotchas

Aider's /run output is appended to context — for big payloads, pipe through `head -20` to avoid context bloat.
If you're on Windows in PowerShell, the bash heredoc above won't work; use the inline /run with the JSON quoted as a single string.

Try it without setup

The interactive playground lets you send live JSON-RPC requests against the A2A endpoint with no install, no auth. Pick a skill, hit send, see the response.
