gtmos-mcp

Read-only CRM audit for Claude: score data integrity, find duplicate clusters and stalled revenue, in your environment through your own token.

An MCP (Model Context Protocol) server that lets Claude Desktop, Claude Code, or any MCP host audit your HubSpot CRM. It runs in your environment, reads with your own HubSpot token, and no new vendor touches your data. Every tool is read-only by construction: nothing in this package writes to a CRM, sends mail, or calls any network API other than your own HubSpot endpoint.

• Zero dependencies. Pure Python stdlib (dependencies = []). Nothing to vet transitively.

• Read-only. Six tools; four audits, a context graph, and a proposal queue that proposes but never applies. No write scopes needed on your token.

• Deterministic scoring. No LLM in the score path; the model reads results, it does not invent them.

• Works offline. Point the tools at a JSON export instead of a live portal and no network call happens at all.

Tools

Install

Requires Python 3.11+.

pip install gtmos-mcp

Or from source:

pip install git+https://github.com/Kai8karma/gtmos-mcp.git

Verify:

gtmos mcp --dry-run

Expected output:

[dry-run] gtmos mcp would serve 6 tools on stdio (protocol 2025-06-18)
  - audit_crm: Score a CRM export or live HubSpot portal for data-integrity leaks.
  - funnel_leak: Analyse deals by stage to find stalled pipeline and where revenue leaks out of the funnel.
  - cortex_scorecard: Score GTM ops health across five dimensions (data quality, lifecycle, routing, automation, reporting) from a CRM export or live HubSpot portal.
  - ops_signals: Terse severity-tagged signal list on the GTM stack itself, not the buyer: routing SLA breaches, property drift, lifecycle integrity breaks, and sync-failure proxies, with counts and top offenders.
  - cortex_graph: Build the Cortex context graph from a CRM export or live HubSpot portal: contacts, accounts (by email domain), owners, sources, and deals, with explicit-only edges and a per-account rollup (owners, unrouted contacts, source conflicts, SLA breaches, open pipeline, last touch, flags).
  - cortex_proposals: Run the Cortex governed agents (router, deduper, lifecycle steward, attribution steward, pipeline steward, schema steward) over the context graph and return a policy-gated proposal queue: each proposal carries targets, a before/after diff, evidence, confidence, and blast radius; proposals that fail the policy (action allow-list, blast-radius cap, confidence floor) are returned as BLOCKED with the reason.

Connect to Claude

Generate the config block (always matches the installed code):

gtmos mcp --config

Then paste it into your MCP host config. For Claude Desktop that is ~/Library/Application Support/Claude/claude_desktop_config.json (macOS):

{
  "mcpServers": {
    "gtmos": {
      "command": "gtmos",
      "args": [
        "mcp"
      ],
      "env": {
        "GTMOS_HUBSPOT_TOKEN": "<your-hubspot-private-app-token>"
      }
    }
  }
}

For Claude Code:

claude mcp add gtmos --env GTMOS_HUBSPOT_TOKEN=<your-hubspot-private-app-token> -- gtmos mcp

Restart the host, then ask: "Audit my CRM and show me the weakest dimension."

Getting a HubSpot token

Create a private app in your HubSpot portal with read-only scopes: crm.objects.contacts.read for audit_crm, crm.objects.deals.read for funnel_leak. cortex_scorecard, ops_signals, cortex_graph, and cortex_proposals reuse both fetch paths, so they need whichever of those two scopes matches the inputs you give them. The token stays in your host config on your machine; this package never stores or forwards it.

No token? Use an export

Every tool accepts a file instead of a live portal:

audit_crm        { "contacts_file": "./contacts.json", "acv": 9000 }
funnel_leak      { "deals_file": "./deals.json" }
cortex_scorecard { "contacts_file": "./contacts.json", "deals_file": "./deals.json" }
ops_signals      { "contacts_file": "./contacts.json" }
cortex_graph     { "contacts_file": "./contacts.json", "deals_file": "./deals.json", "account": "acme.com" }
cortex_proposals { "contacts_file": "./contacts.json", "deals_file": "./deals.json", "policy_file": "./policy.json" }

contacts.json is a JSON array of contact objects (HubSpot export shape: properties.email, properties.firstname, ...). See tests/fixtures/contacts_sample.json and tests/fixtures/deals_sample.json for the exact shapes.

Marketing Cortex

A marketing Cortex is three layers: a context graph, a signal layer, and governed agents. All three ship here, all read-only, all working fully offline against a contacts/deals export - no HubSpot token required.

The governance is the point. Every proposal passes a policy before it is shown - action allow-list, blast-radius cap (records and share of universe), confidence floor - and a proposal that fails stays in the output as BLOCKED with the reason, so you can see what the agents wanted and why they were stopped. Nothing is applied by this package: the queue is for a human, or for a separately authorized system, to act on. Override the defaults with a policy file; requires_human is not a setting and cannot be turned off:

{
  "name": "strict",
  "allowed_actions": ["assign_owner", "merge_duplicates", "review_stalled_deal"],
  "max_blast_records": 10,
  "max_blast_share": 0.10,
  "min_confidence": 0.8
}

Because the graph, the scorecard, and the agents all read the same facts through the same functions, a routing breach in the scorecard is the same breach flagged on the account and the same breach the router proposes to fix. The score and the signal and the proposal cannot disagree.

What a run looks like

Scored 25 records.
Portal integrity score: 77.5 (B).
Duplicate clusters found: 2.
Dimension averages (worst first):
  - freshness: 55.0
  - ownership: 88.0
  - validity: 91.9
  - consistency: 93.6
  - completeness: 94.6
Full report written to: ./audit-out/integrity-report.md

CLI without MCP

The same engines run directly from the shell:

gtmos audit --input contacts.json --acv 9000       # contact integrity audit
gtmos cortex --input contacts.json --deals deals.json  # GTM ops health scorecard
gtmos cortex --graph --input contacts.json --deals deals.json --account acme.com   # context graph, one account
gtmos cortex --proposals --input contacts.json --deals deals.json --policy policy.json  # governed proposal queue
gtmos calibrate --scores s.json --outcomes o.json  # grade the scorer against real outcomes

Architecture

Newline-delimited JSON-RPC 2.0 over stdio, per the MCP stdio transport. The protocol handler (handle_message) is a pure function, message in, response out, so the whole surface is testable without spawning a process. The scoring engines are deterministic and network-free; the only network code is the optional HubSpot fetch, using your token, from your machine.
