Slack vs Zoho Sign: at a glance
What is Slack?
Slack now hosts any A2A agent without Slack-specific code.
Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.
What is Zoho Sign?
Zoho Sign is clearing the exit path off Docusign while stacking up regional legal assurance
Zoho Sign publishes through the Zoho blog, so entries are announcement posts truncated to roughly 350 characters. The recent run splits three ways: legal assurance by jurisdiction — qualified electronic signatures for the EU through SIGN8, pan-India e-Stamping — client surfaces including a native Windows app, and agent access through Zoho MCP, where a prompt can send a document for signature and track it. The newest entry adds template migration from Docusign.

Slack now hosts any A2A agent without Slack-specific code.
◆ Current state
Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.
◆ Where it's heading
Slack is lowering the cost of putting outside agents in front of its users: first skills as code, then MCP pointers for coding agents, now a standard protocol in place of the Slack app model for agents. The platform is positioning itself as the place where agents built anywhere meet the people who use them.
◆ Prediction
Expect more A2A follow-ups, such as agents appearing in Slackbot or skills surfaces and richer Agent Card features, given how fast the agent releases have stacked up since October.

Zoho Sign is clearing the exit path off Docusign while stacking up regional legal assurance
◆ Current state
Zoho Sign publishes through the Zoho blog, so entries are announcement posts truncated to roughly 350 characters. The recent run splits three ways: legal assurance by jurisdiction — qualified electronic signatures for the EU through SIGN8, pan-India e-Stamping — client surfaces including a native Windows app, and agent access through Zoho MCP, where a prompt can send a document for signature and track it. The newest entry adds template migration from Docusign.
◆ Where it's heading
Two motions, both aimed at displacement. Zoho is assembling the assurance levels that let it be used for agreements a standard e-signature cannot carry, jurisdiction by jurisdiction, which is what removes the reason enterprises stay with an incumbent. And it is removing the switching cost directly: bringing Docusign templates across in minutes attacks the specific lock-in that keeps a customer on a platform whose documents are already built there. The MCP work runs alongside, making signature workflows something an agent initiates rather than a person.
◆ Prediction
Template migration is the first piece of a switching kit rather than the whole of it; expect the remaining Docusign artefacts — envelopes in flight, saved recipients, completed-document archives — to follow, since a template alone does not move a live signing operation.
