MCP server

The outreach MCP server for your AI

Lead Scorer's entire outbound motion — finding real companies, scoring them, enriching them, writing the messages — is exposed as 104 tools your assistant can call. Connect it once and outreach becomes something you ask for in a sentence, in the assistant you already have open.

104 tools OAuth 2.1 — no key to copy Claude · Claude Code · ChatGPT · Cursor · Codex Included on the free plan

Never heard of MCP?

Model Context Protocol is an open standard for letting an AI assistant call someone else's software. A server publishes a list of tools; your assistant reads that list and decides which ones to call while it talks to you. Adding the Lead Scorer server to Claude or ChatGPT is roughly like giving it a login to your CRM — except you decide, per action, what it is allowed to finish.

Connect it to your client

Pick your client, follow two or three steps, and sign in with your Lead Scorer account. The tools appear in your next message.

No account yet? Continue anyway: the OAuth browser flow includes account creation and brings you back to your agent after consent. The CRM and MCP access are free, no credit card.

Agent-native setup

From “help me do outreach” to a ready account

  1. 1. Install and sign up

    The plugin adds the MCP and Skills. OAuth opens Lead Scorer; sign in or create the account, then approve access.

  2. 2. Choose only what matters

    Inside the agent, the commercial catalog is deliberately limited to Pro monthly and one-time credit top-ups.

  3. 3. Connect and draft

    Connect email or LinkedIn in a hosted flow, create the ICP and campaign, then review every draft before launch.

Then just ask

No tool names to memorise. These are the kinds of sentences that already work.

  • ›Find 50 SaaS founders in France and draft a campaign.
  • ›Score my leads against my ICP and tell me which ones you rejected and why.
  • ›What's in my pipeline this week?
  • ›Enrich my “Seed-stage SaaS” list and summarise what the ten best companies actually sell.
  • ›Capture everyone who reacted to this LinkedIn post and tell me which ten are worth a note.
  • ›Read the drafts in my October campaign and rewrite every generic first line.
  • ›Compare what you remember about me with my Lead Scorer memory and propose the missing context for review.

What your agent can actually do

Eight categories, 104 tools. Everything below ships today — the tool names are the real ones your agent will call.

Account, billing & onboarding

Create the account during OAuth, read a single readiness snapshot, subscribe to Pro monthly, buy one-time credit top-ups, poll the hosted payment and start email or LinkedIn connection flows without leaving the agent conversation.

  • get_onboarding_status
  • list_billing_offers
  • start_subscription_checkout
  • start_credit_topup
  • get_payment_status
  • start_channel_connection

Discovery from the official registry

Search the French State registry (SIRENE + INPI RNE) by NAF/APE code, headcount and département. Every company comes back with a verified SIREN and the real dirigeant — no invented firmographics. Capture audiences from LinkedIn posts and events, and keep them in sync.

  • search_official_company_registry
  • create_audience_source
  • sync_audience_source
  • fetch_profile_posts

Enrichment & scoring

Enrich a company with its business model, value proposition, target customers, competitive advantage, tech stack and hiring signals. Find verified emails and phone numbers. Score the account and the decision-maker against what you actually sell, and write the reason down.

  • enrich_leads
  • enrich_company
  • find_lead_contact_info
  • create_scoring_config
  • submit_lead_score
  • submit_company_classification

Personal Memory & Context Packs

Keep a private, versioned my-memory.md plus one Markdown document per relationship. Append selected ChatGPT or Claude facts with provenance for free, or process a larger export through an estimated AI run whose unused reservation is refunded. Review facts before reusing a bounded Context Pack in drafting and reply triage.

  • get_my_memory
  • update_my_memory
  • get_relationship_memory
  • list_memory_revisions
  • update_relationship_memory
  • remember_relationship_fact
  • list_memory_sources
  • get_memory_source
  • estimate_memory_source_reprocessing
  • start_memory_source_reprocessing
  • compile_context_pack
  • estimate_memory_ingestion
  • start_memory_ingestion
  • review_memory_proposal

Campaigns & outreach

List the campaigns owned by your account, configure the sender identity and inherited account signature, inspect results, or create a new campaign, attach a sender account, add leads, read the authoring context, write the drafts, and repair the weak ones action by action. Each exact email draft can hold one genuine PDF, up to 2 MB decoded, in private storage; adding or removing it always requires fresh human approval.

  • list_sender_accounts
  • update_sender_account
  • list_campaigns
  • create_campaign
  • update_campaign_senders
  • add_leads_to_campaign
  • add_campaign_step
  • get_campaign_authoring_context
  • write_campaign_drafts
  • list_campaign_actions
  • update_campaign_action_draft
  • upload_campaign_action_attachment
  • delete_campaign_action_attachment

Content Studio

The inbound side on the same connection: an editorial backlog, media uploads, a publishing calendar and scheduled LinkedIn posts. Early access.

  • upsert_content_item
  • create_content_post
  • schedule_content_post
  • get_content_calendar

Agent workflows

Start a workflow run, advance it one step at a time, and read its state — the same replayable run the app shows you, driven from your agent instead of the UI.

  • list_workflows
  • start_workflow_run
  • advance_workflow_run
  • get_workflow_run

CRM read & write

Lists, segments, tags, products, companies and leads. Read what is already there before adding to it, and write back everything your agent learns. Included on the free plan.

  • get_lead_lists
  • get_leads_from_list
  • create_lead
  • update_lead
  • remove_lead_access
  • create_list
  • update_product
  • add_tags_to_lead

Nothing sends without your approval

The agent writes, you launch

Every message the agent produces lands as a draft in your approval queue. Going live is a human action in the app — there is no tool that puts a campaign into sending on its own.

You own the pace

Daily cap and sending window are yours. Outreach is a slow drip you configure, not something an agent can accelerate on your behalf.

You sign in, not a key

OAuth 2.1 on every supported client: you authenticate with your own Lead Scorer account and approve access from the sign-in page. Nothing to paste, nothing to rotate, and you can revoke it whenever you want.

Set up by client and channel

28 short guides — the same server, framed around one client and one channel.

Cold email

LinkedIn outreach

Lead scoring

Lead enrichment

Campaigns

Content publishing

Personal CRM memory

Questions

What is MCP?
Model Context Protocol is an open standard that lets an AI assistant call an external service's functions. Connecting the Lead Scorer MCP server gives your assistant a set of outreach tools it can use during a normal conversation — no plugin to build, no API to wrap.
Do I need an API key?
Not for Claude, Claude Code, ChatGPT or Codex — they use OAuth 2.1, so you sign in with your Lead Scorer account and approve access. Cursor is the exception: generate an MCP API key in Settings and paste it into its config.
Can the agent send emails on its own?
No. The agent writes and queues; every message waits in your approval queue. You approve or edit, you set the daily cap and the sending window, and you press launch in the app.
Can I create my Lead Scorer account from Codex or Claude?
Yes. Install the Lead Scorer Outreach plugin or connect the MCP, then authenticate in the browser. The same OAuth flow lets a new user sign up, verify their email and approve the MCP. Back in the agent, it can read onboarding status, offer Pro or a credit top-up, and start email or LinkedIn connection flows.
Which plans include MCP access?
All of them, including the free CRM. AI-powered tool calls consume the same credits and AI budget they would inside the app.
How many tools does the server expose?
104, across nine categories including CRM, enrichment and scoring, Personal Memory and Context Packs, campaigns, content, and agent workflows.

Building on it?

If you are plugging your own agent in rather than using a chat client, the agent tools page covers the workflow endpoints, the pull-and-submit pattern, and the response format. The skills library has the playbooks that drive these tools, and /llm-info is the machine-readable product summary.
