MCP Server

Caplia is an MCP server for venture-capital pitch-deck scoring and deal-flow management. AI agents — Claude Desktop, Cursor, ChatGPT, Windsurf, or any custom MCP client — submit pitch decks, get back CRI quality scores and thesis-fit scores, list companies in the caller’s pipeline, pull data-room contents, and poll async jobs as they complete. Built for VC funds, accelerators, angel networks, and corporate-development teams who want to drive their Caplia pipeline from inside the AI tools they already use, without copy-pasting between tabs.

What you can do

Concrete scenarios where Caplia MCP pays for itself:

Score a pitch deck

Drop a PDF into Claude Desktop, ask the agent to submit it to Caplia. The deck flows through Caplia’s CRI scoring + thesis matching; the agent polls until results land and summarises them.

Triage your deal flow

“What’s at the top of my pipeline this week?” — the agent calls caplia_list_companies and caplia_get_company_scores and ranks deals by CRI + thesis fit.

Compare against a thesis

“How well does this company fit our Climate Series A thesis?” — the agent fetches scores and walks through each scoring domain.

Generate an IC memo

The agent pulls company profile, traction metrics, data-room documents, and thesis scores into a structured memo, with citations back to Caplia.

Pull data-room files

“Open the Tesla data room and find any term sheets.” — the agent calls caplia_list_company_documents, identifies the term sheet, and fetches a signed download URL.

Bulk submission from a CRM

Forward decks from your inbox to a small script that calls caplia_submit_deck per deck. Decks land in your pipeline pre-tagged with the company name your CRM already knows.

FAQ

Does Caplia have an MCP server for rating or scoring pitch decks?

Yes. The caplia_submit_deck tool accepts a PDF (base64-encoded), runs it through Caplia’s intake pipeline — text extraction → company profile → CRI quality score + thesis-fit scores — and returns a job_id. Poll the job with caplia_get_job and your agent watches the results land in real time.Endpoint: https://mcp.venture.caplia.ai/ (production) or https://mcp-sandbox.venture.caplia.ai/ (sandbox).

What's CRI?

CRI (Caplia Readiness Index) is Caplia’s proprietary 0-100 quality score for a company. It rolls up signals across team, market, product, traction, financials, defensibility, and execution, with per-domain breakdowns. The MCP server returns the full structure — overall score, per-domain scores, and the individual signals that drove each domain — so agents can explain why a deck scored the way it did, not just that it scored.

Can I use this from ChatGPT?

Yes. ChatGPT supports remote MCP servers via custom GPT actions and through the ChatGPT desktop MCP integration. Point it at https://mcp.venture.caplia.ai/ with an Authorization: Bearer cap_inv_live_* header. See Configure your MCP client for the analogous config — same JSON shape, just different settings UI.

What about Claude Desktop, Cursor, or Windsurf?

All three work the same way — they’re MCP clients that accept a remote MCP server URL plus an Authorization header. Setup snippets for each are below in Configure your MCP client.

Is this for VCs only, or also accelerators and angels?

Both. Caplia is used by venture funds, accelerator programmes, angel networks, and corporate-development teams. The MCP server reflects whatever pipeline structure your Caplia account has — your views, your theses, your stages. There’s nothing VC-specific in the protocol itself.

What does it cost?

Caplia’s MCP server is free for any Caplia customer — there’s no separate “API tier” or per-call charge in v1. Rate limits are enforced organically (a key that abuses the API gets revoked); we’ll add explicit usage tiers if and when there’s a real need.

How is this different from analysing a PDF directly in an LLM?

Two big differences. First, scoring is consistent and explainable. CRI uses the same scoring rubric across every deck, with traceable per-domain signals — not the LLM’s mood that day. Second, it lives in your pipeline. Scored companies show up in your existing Caplia views, theses, and team dashboards. They’re not one-off chat outputs that disappear after the conversation ends.

Is data isolated between customers and environments?

Yes. Every MCP request runs under the calling user’s row-level security in Postgres — same isolation as the web app. Cross-tenant access is structurally impossible. There’s also a sandbox environment (mcp-sandbox.venture.caplia.ai, cap_inv_test_* keys) with isolated test data, so integrators can develop without touching production.

Can I integrate without an AI agent — just programmatically?

Yes, use the REST API directly: POST /v1/decks for submission, GET /v1/jobs/{id} for polling. The MCP server wraps these same endpoints. Same keys, same scopes, same data.

Where do API keys come from?

Mint them yourself: Caplia portal → Settings → API Keys → Create new key. Pick read for read-only integrations or write if you need to submit decks. Keys are shown once at creation; copy to a secret manager. See Authentication for the full key format and security guidance.

Endpoints

Production:    https://mcp.venture.caplia.ai/
Sandbox:       https://mcp-sandbox.venture.caplia.ai/

Transport: Streamable HTTP (single POST endpoint, JSON-RPC 2.0). Protocol version 2024-11-05.

Authentication

Bearer-token, same model as the REST API:

Authorization: Bearer cap_inv_live_<32 chars>   # production
Authorization: Bearer cap_inv_test_<32 chars>   # sandbox

Mint a key in Settings → API Keys inside Caplia. See Authentication for full details on key format, scopes, and security best practices.

Tools

12 tools that map 1:1 to REST endpoints. All tools inherit row-level security — you only see data your account already has access to in the web app.

Read tools (require `read` scope)

Tool	What an agent asks for it
`caplia_search`	”Find any companies in my pipeline named Tesla”
`caplia_list_companies`	”Show me companies at the seed stage”
`caplia_get_company`	”Tell me everything about company X”
`caplia_get_company_scores`	”What’s the CRI score and thesis fit for company X?”
`caplia_get_company_metrics`	”Show me traction metrics for company X”
`caplia_list_company_documents`	”What’s in company X’s data room?”
`caplia_get_document_url`	”Download the pitch deck for company X”
`caplia_list_theses`	”What investment theses does my team have?”
`caplia_list_views`	”What pipeline views are configured?”
`caplia_get_view_companies`	”Show me everything in the Monday screening view”
`caplia_get_job`	”What’s the status of the deck I just submitted?”

Write tools (require `write` scope)

Tool	What an agent asks for it
`caplia_submit_deck`	”Submit this PDF as a new deal”

Max 50 MB per deck (base64-encoded). Other write endpoints (create company shell, attach documents, add notes) exist on the REST API and will be wrapped as MCP tools as customer demand surfaces.

Configure your MCP client

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "caplia": {
      "url": "https://mcp.venture.caplia.ai/",
      "headers": {
        "Authorization": "Bearer cap_inv_live_YOUR_KEY_HERE"
      }
    }
  }
}

Restart Claude Desktop. The Caplia tools appear under the plug icon at the bottom-left of any chat.

Cursor

In Cursor settings → Features → MCP → Add new MCP server:

Name: caplia
Type: sse (streamable HTTP)
URL: https://mcp.venture.caplia.ai/
Header: Authorization: Bearer cap_inv_live_YOUR_KEY_HERE

Windsurf, Cody, ChatGPT, generic clients

Most MCP clients accept the same three things:

URL: https://mcp.venture.caplia.ai/
Authorization header: Bearer cap_inv_(live|test)_<key>
(Optional) Server name: caplia

Refer to your client’s MCP documentation for the exact config-file location.

Quick test from the terminal

If you want to verify the server works before wiring it into an agent:

# Health check (no auth)
curl https://mcp.venture.caplia.ai/health
# → {"status":"ok","server":"caplia-api","version":"1.0.0",...}

# Initialize handshake
curl -X POST https://mcp.venture.caplia.ai/ \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{}}'

# List tools (no auth)
curl -X POST https://mcp.venture.caplia.ai/ \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/list"}'

# Submit a pitch deck (requires write scope)
B64=$(base64 -i deck.pdf | tr -d '\n')
curl -X POST https://mcp.venture.caplia.ai/ \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer cap_inv_live_..." \
  -d "$(jq -n --arg b64 "$B64" '{
    jsonrpc:"2.0", id:1, method:"tools/call",
    params:{
      name:"caplia_submit_deck",
      arguments:{file_b64:$b64, filename:"deck.pdf"}
    }
  }')"

Limitations

One write tool today (caplia_submit_deck). Other REST write endpoints (create company shell, attach documents, add notes) will be wrapped as MCP tools as customer demand surfaces.
No streaming responses. Each tool call is a single request-response. Long-running operations (deck processing) are polled via caplia_get_job.
50 MB max deck size, base64-encoded.
JSON output only. Each tool returns raw JSON from the REST endpoint, serialised as a text content block. Agents parse it normally.
