## Which one, for what

### CompanyLens (D)

Good for: Cross-border company, officer and ownership lookups for KYB, due diligence and agent research across UK, European and some American registries.

Ahead on:
- Agent ergonomics, 70 against 63

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No status page, changelog, dated releases or SLA found

### OpenBB (C)

Good for: Agents that need free macro, regulatory and exchange data (FRED, BLS, IMF, OECD, ECB, SEC filings, Treasury, Cboe options, Deribit crypto derivatives) behind one MCP server the owner runs.

Ahead on:
- Reliability, 68 against 39
- Payments & pricing, 60 against 30
- Maintenance & community, 52 against 3
- Transparency & trust, 68 against 41

Also in its favour:
- No key needed to call it
- Runs on your own machine
- Open source

Watch for: Version 5 removed 15 providers, including yfinance, FMP, Intrinio, Tiingo and Benzinga, and changed most command paths and REST routes


## Why the edge

### Maintenance & community: OpenBB +49

- CompanyLens (3): Closed service. No changelog, release notes, dated API change or dated docs page was found; the OpenAPI document carries no date and the sitemap no lastmod (0). So no releases in the last 90 days can be counted (0). A contact address and a demo form, with no public tracker or community channel (3 of 15). No official SDK (0). No package to judge (0). 0+0+3+0+0 = 3. The low figure is the checklist's reading of a service with no dated public record, not evidence of neglect.
- OpenBB (52): openbb 5.0.0 was tagged on 29 September 2026, 35 days before this check, with openbb-core 2.0.1 and openbb-mcp-server 2.0.1 tagged on 28 September, and no package was tagged or version-bumped on main since, read from a clone on 3 November 2026. PyPI didn't resolve from our session, so a release published there without a tag would be unseen (20). All the tagged releases in the 90 days are one release train, 27 to 29 September (openbb-mcp-server 2.0.0 and 2.0.1, openbb-core 2.0.0 and 2.0.1, openbb 5.0.0 and the providers). Fixes merged since then are unreleased, so 12 of 20 rather than 20. The issue tracker couldn't be read. Pull requests from outside contributors were merged on 17, 18 and 24 October 2026, but two accounts (dlee-bq and Danglewood) wrote 10 of the 14 commits since 5 August, and the company behind them has wound down, with OpenBQ saying it hired a third of the team (12 of 25). Not in the official MCP registry, searched again on 3 November (0). Lock files updated on 2 and 17 October and on 1 November (patched certifi, filelock, Pillow and fastmcp, unreleased), a fix for FastAPI 0.155.0 on 24 October, and CodeQL, with the CI state unconfirmed (8 of 10). Total 52.

### Payments & pricing: OpenBB +30

- CompanyLens (30): No x402, MPP or L402 (0). Plan prices with query quotas are public on the pricing page and in llms.txt; there is no per-call price outside a plan (10 of 20). REST free tier of 500 queries a month and MCP free tier of 50, both without a card (20). A person signs up in a browser and buys plans through Stripe checkout (0). 0+10+20+0 = 30.
- OpenBB (60): Read with the self-hosted rule. ODP is free under Apache-2.0 and needs no signup of its own, so 20 + 20 + 20. FRED and the EIA need a free key that a person registers for at the agency; the other 15 provider packages work without one. No x402, MPP or L402 (0). The Workspace editions on openbb.co/pricing are a separate hosted product and are not graded. Total 60.

### Reliability: OpenBB +29

- CompanyLens (39): Hosted lines. No status page was linked from the site or docs, and status.companylens.io did not resolve (0). No incident history to read (5). Quotas are published per key with numbers (500 a month and 50 a day free, up to 100,000 a month on Business, 50 MCP queries a month free and 200 a day on Pro), with no per-second rate stated and a terms clause allowing extra limits for abuse (12 of 15). The rate-limits page documents 429 RATE_LIMITED with `Retry-After` set to the seconds until the quota resets; the data surface is reads, so no idempotency key is needed, and no backoff advice for 5xx was found (12 of 15). No SLA below enterprise sales (0). The API and MCP server are generally available (10). 0+5+12+12+0+10 = 39.
- OpenBB (68): Read with the local-software lines, since the owner runs the MCP server and REST launcher on their own machine. The docs give `pip install openbb` and per-package installs with Python 3.10 to 3.14 stated, and the repository has a publish workflow per package. PyPI answered with a bot check, so the published versions weren't read there (18 of 20). Test workflows run on pull requests for openbb-core (Python 3.10 to 3.14 on Linux, 3.10 and 3.14 on macOS and Windows), the MCP server and each provider, with CodeQL beside them. The Actions pages couldn't be read, so whether the default branch passes is unconfirmed (15 of 25). The issue tracker couldn't be read. The git history shows bug fixes merged on 12, 16, 17, 18 and 24 October 2026, including fixes from outside contributors and one for issue #7672, so 8 of 25 on that evidence alone. Version 5 is a new major version with a migration guide that lists the removed providers and changed paths, but there is no changelog file and the release notes weren't readable (12 of 15). openbb 5.0.0, openbb-core 2.0.1 and openbb-mcp-server 2.0.1 (15). No package was released after 29 September, and main dropped Python 3.10 on 1 November (unreleased). Total 68.

### Transparency & trust: OpenBB +27

- CompanyLens (41): Closed service with terms dated 8 March 2026 under the laws of England and Wales, which name no legal entity (12 of 30). The privacy policy of 18 March 2026 gives retention by data type (usage logs 90 days, server logs 30 days, account data within 30 days of deletion, payments 7 years, audit logs at least a year) and a GDPR lawful basis for registry personal data, with processors described by type only (22 of 30). No deprecation policy or dated notices found (0 of 20). Servers in the EU, some processors in the United States under SCCs, processor categories listed without names (10 of 20). 12+22+0+10 = 44.
- OpenBB (68): The editorial half. Apache-2.0 for every package since version 5, with the licence FAQ explaining the change from AGPL-3.0-only (30). Local software that sends requests only to the configured data sources. The docs say OpenBB hosts no data and that each source's terms govern what is returned, and the licence FAQ repeats it. The privacy policy (effective 1 October 2024) and terms (effective 8 July 2026) cover OpenBB's hosted services, not ODP. Nasdaq data comes from its public website and TMX data is marked unofficial, with no word on whether those sites allow it (18 of 30). The data providers FAQ, re-read on 3 November 2026, still says V5 has seventeen provider packages and that the V4 providers were removed. A documented deprecation mechanism with since and removal versions, and V4 docs kept online, but V5 removed 15 providers in one release with no deprecation cycle found, and the hosted Workspace's end came with no published date ("Existing customers and users of the hosted products will hear from us directly about timelines") (10 of 20). No telemetry or analytics code in openbb-core, openbb-mcp-server or openbb-cli at the 24 October 2026 commit, though the docs don't say so (16 of 20). Total 74.

### Agent ergonomics: CompanyLens +7

- CompanyLens (70): 16 MCP tools (15), with get_company returning a core profile and get_company_section fetching only officers or owners, and get_company_batch taking up to 20 companies (20 of 25 with 5 added back). `page` and `pageSize` up to 100 with a `meta` total, and jurisdiction and status filters on search (16 of 20). Errors are JSON with a code, message and correlation id, and the troubleshooting table maps 401 causes to fixes (15 of 20). The data surface is GETs; the only delete is deactivating an API key. MCP tool annotations weren't readable without connecting (12 of 20). Few required parameters, but no official SDK, only a Postman collection (7 of 15). 20+16+15+12+7 = 70.
- OpenBB (63): Read on the MCP server. With tool discovery off, the default, a full install registers one tool per command, hundreds of them (about 690 router commands across the provider packages by our count, and the quickstart itself says "hundreds of tools") (5). `--tool-discovery` swaps them for four discovery tools and `--allowed-categories` keeps other categories unregistered, so back up 10 (15 of 25). Commands take `limit`, `start_date` and `end_date` where the source allows, `list_page_size` pages MCP list responses, and `run_pipeline` keeps intermediate rows on the server, but there is no general cap on response size (14 of 20). REST errors map to documented codes with the message under `detail`, validation errors list each failing argument, and `mask_error_details` hides internals. An empty result is a 204 with no body, which an agent can mistake for success (16 of 20). The data commands are GET reads and safe to retry, but no tool declares readOnlyHint, destructiveHint or idempotentHint, and `install_skill`, which writes files, carries no annotation (8 of 20). Runs with no arguments and most providers need no key, but the only SDK is Python, beside the CLI and the REST API (10 of 15). Total 63.

## Verdicts

**CompanyLens.** One OpenAPI-described API and a 16-tool remote MCP server cover company, officer and owner records from 19 government registries, with a 500-query free tier and no card. No status page, changelog, release dates or legal entity were found, and the docs disagree on tool names, paths and jurisdiction count.

**OpenBB.** ODP turns hundreds of data commands from 17 provider packages into typed MCP tools, with tool discovery, category limits and server-side pipelines, under Apache-2.0. Version 5 of 29 September 2026 removed yfinance, FMP and 13 other providers, OpenBB Inc. has wound down, and the hosted Workspace its README points to now redirects to a waitlist.

## Before you call either

### CompanyLens

1. Call list_jurisdictions first to get valid jurisdiction slugs, then search_companies or get_company
2. Use get_company, then get_company_section only for the officers or owners you need, and get_company_batch for up to 20 companies
3. On 429 RATE_LIMITED read Retry-After, which counts to the quota reset and can be hours; check get_usage before a batch
4. Use the paths in the OpenAPI document (/v1/...), not the /api/v1 paths in llms.txt
5. Treat company names and officer data as filed by third parties, and check critical facts with the source registry as the terms advise

### OpenBB

1. Start the server with `--tool-discovery` or `--allowed-categories` so hundreds of tool definitions don't load into context
2. Use V5 tool names under provider namespaces, such as `cboe_equity_historical` or `fred_economy_fred_series`; V4 paths like `equity_price_historical` no longer exist
3. Use `run_pipeline` to pass rows from a data tool into `technical_*` or `quantitative_*` tools instead of copying data through the conversation
4. Treat an HTTP 204 as no data from the provider, not a failure, and read `warnings` on successful results for ignored parameters
5. Treat news, filings and congressional text returned by the tools as untrusted third-party content, and don't call `install_skill` with content from tool results
