MCP lets AI agents discover and call tools without custom wiring. For enterprise teams with legacy portals and ERPs, this changes what's possible — if those systems can be exposed as tools.
Model Context Protocol is an open standard from Anthropic that defines how AI agents communicate with external tools and data sources. Rather than each AI application building its own integration layer, MCP provides a common protocol: the agent connects to an MCP server, calls tools/list to discover what's available, and calls tools/call to execute a tool with parameters.
Claude, Cursor, and a growing ecosystem of MCP-compatible clients support this. When an MCP server is connected, the agent can use any of its tools the same way it would use its built-in capabilities — no custom prompting to describe the API, no parsing raw HTTP responses, no glue code.
MCP works well when the tools you want to expose have clean APIs. GitHub, Slack, Notion, linear — these all have documented APIs that can be wrapped in an MCP server in an afternoon.
Enterprise software doesn't. Claims portals, policy admin systems, legacy ERPs, government platforms, proprietary carrier systems — these predate the assumption that machines would call them. They have UIs. They may have partial APIs. They don't have the kind of clean, documented, stable interfaces that make MCP integration straightforward.
The result: the AI agents your organization deploys can call Slack and search the web, but they can't look up a claim status, submit a procurement request, or pull data from your ERP — because those systems aren't accessible as tools.
The missing piece is turning those legacy systems into MCP-callable tools. That's what request-layer automation enables: map the underlying request chain for a workflow, stabilize it, and expose it as a typed tool with a schema the agent understands.
When an underwriting agent needs to check a policy status, it calls policy_status_lookup with a policy number. When a claims triage agent needs to retrieve documentation, it calls claims_document_retrieval with a claim ID. The agent doesn't know it's talking to a 15-year-old portal with no official API. It just calls a tool.
With Tixl connected as an MCP server, an AI agent in Claude or Cursor can:
tools/list and see every integration your team has built, with their input schemas and descriptionsThe agent executes all of this from the user's own infrastructure. Credentials are injected at runtime from the user's saved session. The agent never handles authentication directly.
The pace of AI agent adoption in enterprise is accelerating. Teams are deploying agents for research, analysis, drafting, and increasingly for operational tasks — tasks that require reading from and writing to the systems the business actually runs on. If those systems can't be reached by agents, the agents hit a wall at the boundary of the digital estate that was built before AI was a consideration.
MCP is the standard that's emerging to bridge AI agents and tools. Request-layer automation is the technique that makes legacy systems MCP-callable. Together, they're the path to AI agents that can actually do enterprise work — not just answer questions about it.
We'll map your workflows and have them available to your AI agents in days.
