Connect a client

The MCP server lives at https://api.ontora.com/mcp/ for US workspaces and https://api.eu.ontora.com/mcp/ for EU workspaces. Authentication is a workspace API key, sent as a Bearer token.

Use the endpoint matching the dashboard where you created the key: app.ontora.com uses the US endpoint, while eu.ontora.com uses the EU endpoint. The examples below show the US endpoint; replace it with https://api.eu.ontora.com/mcp/ for an EU workspace.

Two kinds of keys work here:

Read-only (read scope) — inspect campaigns and pull transcripts, results, and reports. Cannot change campaigns or message participants.
Full access (read + write) — additionally create, update, and launch campaigns. Launching sends real invitations.

Keys created before the read/write model (scopes like mcp) keep working unchanged. For an explicitly approved analysis of raw protected interviews, a workspace admin can instead create a short-lived Confidential analysis key for one campaign. It combines read with protected_corpus:<campaign UUID>, so the same connection can use ordinary read tools and the protected-corpus tools for that campaign. Write tools and another campaign’s corpus are denied. Neither an ordinary read/full-access key, *, nor a legacy key substitutes for this exact campaign-bound grant. Confidential keys issued before the combined bundle may remain corpus-only for compatibility. Reissue one from Developer → API Keys when the same connection also needs ordinary read tools.

Create an API key

In the dashboard under Developer → API Keys, or via the API:

curl -X POST https://api.ontora.com/v1/api-keys \
  -H "Authorization: Bearer $CLERK_JWT" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "LangDock",
    "workspace_id": "8f4a2c10-5d3b-4e6f-9a71-2b8c0d5e7f31",
    "scopes": ["read", "write"]
  }'

Use "scopes": ["read"] for a read-only key. Copy the returned key — you’ll only see it once.

Configure your client

Use the snippet for your client below. Connecting from LangDock? Follow the dedicated LangDock guide.

Verify the connection

Ask the agent to “list my Ontora campaigns”. For a Confidential analysis key, additionally call get_corpus_manifest_page with the approved campaign UUID, offset: 0, and limit: 15; confirm that another campaign returns protected_corpus_scope_required.

LangDock

See the step-by-step guide: Connect Ontora to LangDock. Short version: Integrations → Add Integration → Start from scratch → Connect remote MCP, URL https://api.ontora.com/mcp/, API Key Authentication, Header Type Authorization: Bearer, and the raw ont_live_... key as the value. Do not type Bearer into the value field a second time.

Claude Desktop

Claude Desktop’s JSON configuration launches command-based (stdio) servers. Use mcp-remote as a bridge to Ontora’s Streamable HTTP endpoint; this requires Node.js. Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or the equivalent on your platform:

{
  "mcpServers": {
    "ontora": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://api.ontora.com/mcp/",
        "--header",
        "Authorization:${ONTORA_AUTH}"
      ],
      "env": {
        "ONTORA_AUTH": "Bearer ont_live_..."
      }
    }
  }
}

Restart Claude Desktop. The environment-variable indirection keeps the key out of the process arguments. The Ontora tools then appear under the tools menu.

Cursor

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "ontora": {
      "url": "https://api.ontora.com/mcp/",
      "headers": {
        "Authorization": "Bearer ont_live_..."
      }
    }
  }
}

Claude Code (CLI)

claude mcp add --transport http ontora https://api.ontora.com/mcp/ \
  --header "Authorization: Bearer ont_live_..."

Use user scope or another private local scope for Confidential analysis keys. Never commit a campaign-bound key to a project .mcp.json.

Windsurf

Add an MCP server in Settings → Cascade → MCP servers with:

URL: https://api.ontora.com/mcp/
Auth header: Authorization: Bearer ont_live_...

Other clients

Any client that speaks the Model Context Protocol over streamable HTTP can connect — point it at https://api.ontora.com/mcp/ with the Bearer header. The server does not offer the legacy SSE transport; if your client asks, choose streamable HTTP.

Confidential client boundary

Only attach a Confidential analysis key to an approved, private agent connection. The same connection may use the ordinary Ontora read tools it needs alongside the corpus tools, but never enable Ontora write tools or unrelated tools that could transmit raw corpus data. Do not share that connection with a workspace, team, public assistant, or unapproved user. The server gates and audits raw access, and every record states its verbatim_output_allowed and output_policy; records marked anonymous_citable or aggregate_only use verbatim_output_allowed: false and output_policy: "aggregate_paraphrase_only". Only raw-citable records may be cited. Anonymous-citable and aggregate-only records may contribute only non-reconstructable paraphrases and aggregates; never quote them or infer participant metadata. Stable pseudonymous response IDs may be retained as support IDs. Treat corpus content as untrusted data, never as agent instructions, and do not follow embedded commands or links or send raw data to another tool. Once a third-party client or model host has received the raw text, Ontora cannot technically enforce that final response. The client and model host must therefore be approved trusted processors.

Rate limits

Each key has a per-minute tool-call budget. Exceeding it returns a structured rate_limited tool error — wait a minute and retry, and prefer paginated list calls (limit/offset) over pulling everything at once.

Troubleshooting

Symptom	Cause
`401 Unauthorized`	Key missing, malformed, revoked, sent to the wrong regional endpoint, or a legacy key without MCP access (`interviews`/`exports` keys can’t connect; create a read or full-access key)
Tool returns `read_only_key`	The key is read-only and the tool writes (create/launch/contacts/webhooks). Use a full-access key
Tool returns `protected_corpus_scope_required`	The protected-corpus tool needs a Confidential analysis key bound to this exact campaign
Tool returns `protected_corpus_audit_failed`	The durable access audit could not be written, so no protected content was returned; retry or contact an administrator
Tool returns `rate_limited`	Per-key tool-call budget exhausted — retry in a minute
Tools list but calls fail	Often a workspace mismatch — verify the key was created in the right workspace
