Connect Reachable to Claude, ChatGPT, Le Chat and n8n
Add the server once. Your agent tracks the companies you care about, tells you when one of them moves and cites the source and date of every data point.
MCP server URL
https://withreachable.com/v1/mcp
We give you the prospecting infrastructure. You do what you want with it.
The data is already there
Every French company (SIRENE, RNE, BODACC, public contracts, labels), merged and matched, each with its source and date.
The plumbing is done
Sources, chained steps, filters, output to webhook, MCP and API. Nothing to host, no queue to set up, no dozen supplier accounts to open.
You build your own funnel
The granularity depends on the prospecting you target: CSV, CRM, Google Maps or Google search as input, then signals and AI steps.
One price per run, shown upfront
Each check has a fixed price, whether it finds something or not. Calls to your own APIs are free; a failure on our side costs nothing.

The server's 27 tools
Each tool declares whether it is read-only or writes to your account (credits charged, watch created or modified), so your client asks for confirmation at the right time. Each tool also describes itself to your agent once connected. The price of each signal is on the Pricing page.

What you can ask your agent
“Track restaurants in the Rhône created this year and tell me, each week, which ones just changed director or entered insolvency. Tell me the cost first.”
The agent shows the volume and cost before creating the watch, then exports the newly qualified companies of each run.
“How many active plumbing companies (NAF 43.22A) are there in the Rhône?”
Free count, before any search.
“List plumbing companies in the Rhône created since 1 January 2026. Estimate the cost first.”
The agent knows the exact cost before running the search.
“Give me the profile of SIREN 552 100 554, with its RGE, Qualiopi or organic labels.”
Public and label blocks, each with its source and date.
“Which public contracts have been awarded to companies in the Rhône since the start of the month?”
contract.awarded signals, dated and sourced.
“Find construction companies in the Nord that opened insolvency proceedings this year.”
Filter by the insolvency.opened signal over the period.
“For these five SIRENs, tell me which are closed and which recently obtained a label.”
SIRENE status and certification.obtained signals.
