Connect dossaro to your research workflow

Add dossaro to Claude or ChatGPT and run source-backed register research from your own workspace.

dossaro exposes a read-only Model Context Protocol server for source-backed private-market, company-register and document research. It gives supported agent hosts a stable tool layer for searching registers, resolving entities, listing public documents and parsing readable text where the underlying source allows it.

Endpoint and auth

Use this MCP server URL in supported connector hosts:

text

https://mcp.dossaro.com/mcp

Authentication is OAuth. The connector host opens a dossaro authorization screen, the user signs in, and dossaro grants the host access to the MCP tools for that account. Tool calls are account-scoped and may consume credits or hit subscription limits.

The MCP does not receive the user's ChatGPT or Claude password. Connector setup is controlled by the host, while dossaro controls account authorization, credit limits and source access.

For the full signup, organization, employee join and OAuth approval flow, see Account, organization and OAuth flow.

How agents should use it

Use the MCP as a register evidence layer, not as an autonomous legal or investment decision maker.

For one company:

Call search_entities first, preferably with exact register identifiers when the user provides them.
Keep the returned entityRef. Use it for follow-up calls instead of reconstructing source-native identifiers.
Call get_entity_details for one-hop evidence surfaces such as profile, officers, documents, financials and insolvency.
Call list_documents before parse_document when readable source text is needed.
Keep the returned documentRef. Pass that handle to parse_document instead of rebuilding row keys, publication IDs or register fields.
Treat partial, blocked, unavailable or credential-gated source responses as review reasons, not as negative evidence.

For longlists, use the batch primitives for repeated independent searches, but keep the row composition in the calling agent. render_research_table is for presenting already-researched rows; it does not query registers or validate facts.

Tool reference

Group	Tools	Use
Discovery and account	`get_capabilities`, `get_usage_limits`, `submit_feedback`	Inspect coverage, source operations, account credits and report source/tool issues.
Entity research	`search_entities`, `search_entities_batch`, `resolve_entity`, `get_entity_profile`, `get_entity_details`	Find candidates, normalize one selected result and fetch source-backed profile or detail evidence.
Evidence and documents	`search_evidence`, `search_evidence_batch`, `search_relationships`, `list_documents`, `list_documents_batch`, `parse_document`	Search filings/notices/regulatory evidence, list public document refs and parse readable text, OCR or tables where available.
Advanced and output	`source_raw`, `render_research_table`	Run allowlisted source-native inspection operations, or render final agent-composed research rows as a read-only table.

Important limits

dossaro is not legal, tax, financial, investment, compliance or official registry advice.
The MCP does not synthesize shareholder rows, cap tables, beneficial-ownership conclusions, structured revenue, EBITDA or other financial facts.
China core coverage currently means Shenzhen SZCredit only, not national GSXT access or nationwide China register coverage.
Relationship surfaces are source-backed one-hop evidence only. Empty officers, PSC/control or relationship arrays must not be treated as proof that no ownership or control relationship exists.
Public/free source limits apply. Some registers expose only search/profile data, some documents are paid, login-bound or credential-gated, and some parsers only work for selected public artifacts.
source_raw is allowlisted source-native inspection, not arbitrary URL fetching.
Parsed text, OCR and tables are evidence aids. Human review is required before relying on source material.
