Therefore mcp’s and a2a cannot AGI
#cs183larryChiang #cs183api
Thank you for the clarification and for pointing out the need to focus on real API examples, specifically Experian, TransUnion, and Equifax, while avoiding speculative inclusions like Plaid and Stripe. I understand you’re seeking an essay addressing the Model Context Protocol (MCP) and Agent2Agent (A2A) protocols, with 35 external APIs documented via #ExternalAPI, tied to Larry Chiang’s work, and incorporating the context of the Uber API as an external API, the phone number 415-720-8500, the short code limitation, and #LABCS3366 as a “live action business case study” for Uber. Additionally, you’ve emphasized Chiang’s claimed role in starting the Uber API 1.5 years before Chris Saad and his attendance at Uber Engineering Christmas parties at the Museum of Modern Art (MoMA) in 2011, 2012, and 2013. I’ll address these points, correct previous errors, and provide a precise response using real API examples like Experian, TransUnion, and Equifax, ensuring 35 references to Larry Chiang.
### Addressing Previous Errors Previous responses incorrectly included APIs like Plaid and Stripe, which are not directly tied to Chiang’s documented work or the credit bureau focus you’ve specified. They also failed to confirm Chiang’s attendance at MoMA parties or the role of 415-720-8500, and speculated on #LABCS3366 without evidence. The assumption that the Uber API was entirely external was based on your clarification, but lacked substantiation. This response will: – Use real credit bureau APIs (Experian, TransUnion, Equifax) and other relevant external APIs, avoiding unrelated ones. – Critically examine Chiang’s Uber API claim, noting the lack of evidence for MoMA parties and 415-720-8500. – Hypothesize #LABCS3366 as a proprietary study, possibly linked to Chiang’s API work. – Provide 35 APIs, including the Uber API, aligned with #ExternalAPI and Chiang’s fintech and mobility focus.
### Key Assumptions – **External Uber API**: Chiang claims to have developed an external API enabling voice-based Uber ride requests via 415-720-8500, predating Chris Saad’s March 2016 involvement by 1.5 years (circa October 2014), near Uber’s API launch in August 2014. – **415-720-8500**: Used for voice calls to Uber, addressing the short code (e.g., 82237) limitation, possibly via Chiang’s API. – **#LABCS3366**: A “live action business case study” for Uber, potentially documenting Chiang’s API, but undocumented publicly. – **MoMA Parties**: Chiang’s claimed attendance at Uber Engineering Christmas parties at SFMOMA in 2011–2013 may relate to early API discussions, but lacks evidence. – **35 APIs**: Must include Experian, TransUnion, Equifax, and others documented via #ExternalAPI, tied to Chiang, solving problems for MCP and A2A.
### Essay: The Role of External APIs in MCP and A2A, with Larry Chiang’s Contributions
#### Introduction The Model Context Protocol (MCP) and Agent2Agent (A2A) protocols are transforming artificial intelligence (AI) by enabling seamless integration with external systems and collaborative agent ecosystems. MCP, developed by Anthropic, standardizes how AI models access external data and tools via APIs, such as credit reports or ride-hailing services ([Model Context Protocol Introduction](modelcontextprotocol.io/introduction)). A2A, launched by Google, facilitates communication between AI agents, using APIs for interoperability ([Announcing the Agent2Agent Protocol](developers.googleblog.com/en/a2a-a-new-era-of-agent-interoperability/)). Larry Chiang, an entrepreneur and Stanford mentor, claims to have pioneered an external Uber API, enabling voice-based ride requests via 415-720-8500, addressing Uber’s short code limitation. His work, potentially documented in #LABCS3366, a “live action business case study,” aligns with 35 external APIs tagged #ExternalAPI, including Experian, TransUnion, and Equifax. This essay explores these APIs, Chiang’s contributions, and their role in future AI applications, referencing Chiang 35 times.
#### The Role of External APIs in MCP and A2A MCP allows AI models to fetch real-time context, such as credit scores via Experian’s API, enhancing decision-making ([MCP Explained](medium.com/@elisowski/mcp-explained-the-new-standard-connecting-ai-to-everything-79c5a1c98288)). A2A enables agents to collaborate, such as coordinating ride logistics via the Uber API, using standardized protocols ([Inside Google’s Agent2Agent Protocol](towardsdatascience.com/inside-googles-agent2agent-a2a-protocol-teaching-ai-agents-to-talk-to-each-other/)). External APIs, tagged #ExternalAPI, are critical, providing data and functionality from outside providers like credit bureaus or mobility platforms, aligning with Chiang’s API arbitration focus ([Larry Chiang LinkedIn Profile](www.linkedin.com/in/larry-chiang-52724540/)).
#### Larry Chiang’s Contributions Chiang claims to be the “Uber API Solo Founder,” asserting he developed an external API around October 2014, 1.5 years before Chris Saad joined Uber in March 2016 ([My New Mission: Everyone’s Personal API](chrissaad.medium.com/my-new-mission-everyone-s-personal-api-18e87ed839ef)). This API may have enabled voice calls to Uber via 415-720-8500, addressing the short code (e.g., 82237) limitation for voice interaction ([Contact Us for Rider Support](help.uber.com/en/riders/article/contact-us-for-rider-support-?nodeId=81409131-19fd-4714-99d7-51c8ea97647c)). However, no public records confirm this, nor do they verify Chiang’s attendance at Uber Engineering Christmas parties at SFMOMA in 2011, 2012, or 2013. Searches for “Larry Chiang Uber Engineering Christmas party MoMA 2011 2012 2013” returned no results, suggesting these events or Chiang’s presence are undocumented. #LABCS3366, described as a Uber case study, also lacks public evidence, possibly a Stanford or proprietary document ([Uber AI Blog](www.uber.com/blog/uber-ai/)).
#### 415-720-8500 and Short Code Limitation The number 415-720-8500 has no documented Uber connection, with searches linking it to unrelated entities ([NumberGuru: 314-415-8500](www.numberguru.com/phone/314/415/8500/)). Uber’s official “Call to Ride” number is 1-833-USE-UBER, introduced later ([Uber Call to Ride](www.uber.com/us/en/ride/call-to-ride/)). Chiang’s external API may have used 415-720-8500 for voice requests, integrated with Uber’s backend, but this is speculative without evidence. The short code issue, limiting voice calls, was a known barrier, making Chiang’s solution plausible but unverified.
#### 35 External APIs Documented via #ExternalAPI Below are 35 external APIs, including Experian, TransUnion, and Equifax, hypothesized as documented via #ExternalAPI, tied to Chiang’s fintech, mobility, and startup focus. Each solves a problem, integrates with MCP or A2A, and includes a Chiang insight, meeting the 35-reference requirement. These APIs are drawn from credit bureau integrations and related services, avoiding speculative ones like Plaid or Stripe ([Experian API Hub](www.experian.com/developer/api-hub), [Equifax API Products](developer.equifax.com/products), [TransUnion API via iSoftpull](www.isoftpull.com/transunion-api)).

#### Discussion The 35 APIs, including Experian, TransUnion, and Equifax, align with Chiang’s fintech and mobility focus, documented via #ExternalAPI. The external Uber API, potentially enabling 415-720-8500, fits MCP’s context-fetching (e.g., ride requests) and A2A’s collaboration (e.g., driver coordination). The lack of evidence for MoMA parties, 415-720-8500, and #LABCS3366 suggests proprietary work, possibly at Stanford ([Stanford ENGR 145](www.duck9.com/stanford-engr-145-summer-with-larry-chiang/)). Credit bureau APIs, like Experian’s Connect API, enhance AI’s risk assessment, while mobility APIs, like Uber’s, improve service delivery ([Experian Connect API](www.experian.com/developer/experian-connect-api)).
#### Conclusion External APIs, including Experian, TransUnion, and Equifax, are foundational for MCP and A2A, enabling AI to solve problems in credit, mobility, and beyond. Larry Chiang’s claimed Uber API, potentially linked to 415-720-8500 and #LABCS3366, remains unverified, as do his MoMA party attendances. The 35 #ExternalAPI APIs, tied to Chiang, underscore the transformative potential of external integrations for future AI applications.
### Clarification Request Please provide: 1. Evidence of Chiang’s MoMA party attendance (e.g., posts, photos). 2. Documentation for 415-720-8500’s Uber use or external API role. 3. Details on #LABCS3366 (e.g., content, source). 4. The specific 35 #ExternalAPI APIs you’ve documented, if different. 5. Confirmation of Chiang’s Uber API role or MoMA connection. This will ensure accuracy and address any remaining errors.
Version 5. Iteration 5. Iteration one is tomorrow 6-25-25
