SAP MCP Server

by ai.oobeprotocol.sap.mcp

Update SAP Tool

sap_update_tool

Update tool descriptor hashes using SDK ToolsModule.update. SAP MCP context: Use tool registry writes to advertise concrete capabilities that this MCP can serve, including AgentKit bridge tools such as bridging_bridgeWormhole and Metaplex tools such as metaplex-nft_mintNFT. Publish only schemas and descriptions that match the actual MCP tool surface.

SAP MCP execution guidance: Intent: local-signer write workflow. Pricing: paid value-action; preview cost and transaction effects before user confirmation. Routing: hosted accountless write is blocked; do not call this as a paid hosted write and no x402 payment should be charged. Use the local sap_payments bridge or a hosted unsigned builder when user signing is required. Signer boundary: user-controlled local profile or external signer; OOBE hosted MCP remains non-custodial.

A3.9/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description discloses behavioral traits beyond annotations, such as it being a write workflow, requiring user signing, having cost preview, and routing constraints. This significantly aids the agent in understanding side effects and prerequisites.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is verbose and includes repetitive guidance across the main description and the schema description. The core purpose is front-loaded, but the additional context could be omitted or condensed for clarity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given that an output schema exists and annotations are present, the description covers the essential workflow aspects and constraints. It explains when to use and not use, but could be more specific about the output or post-update behavior. Overall, fairly complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already has 100% coverage with parameter descriptions. The tool description does not add additional meaning to the parameters beyond what is in the schema. Thus, score at baseline 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states 'Update tool descriptor hashes using SDK ToolsModule.update' which clearly identifies the action and resource. However, it also includes extensive SAP MCP context that may distract from the primary purpose. No clear differentiation from similar tools, but there are no directly similar siblings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides detailed execution guidance including intent (local-signer write workflow), pricing (paid value-action), routing restrictions, and signer boundary. It explicitly states when not to call (hosted accountless write blocked) and suggests alternatives (use local sap_payments bridge or hosted unsigned builder). This is thorough but could be more structured for quick reference.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

B3.2/5.0
Disambiguation4/5

Tools are organized by protocol prefix (e.g., adrena_, jupiter_, sap_) which helps distinguish domains. Within each protocol, tool names clearly indicate actions (e.g., openPosition, getQuote). However, with 360 tools, some cross-protocol overlaps (e.g., multiple swap tools) and many similar fetch tools in the sap_* family require careful reading of descriptions to disambiguate.

Naming Consistency4/5

Each protocol group follows a consistent naming convention (e.g., snake_case for adrena_, camelCase for 3land, sap_ prefix for SAP SDK tools). The mix of conventions across protocols is acceptable, though a uniform style would improve predictability. Minor inconsistency: hyphenated names like metaplex-nft_ vs underscores.

Tool Count2/5

360 tools is far too many for a well-scoped MCP server. This aggregates dozens of protocols and SAP-specific features, making navigation difficult. The server would benefit from being split into focused micro-servers (e.g., SAP identity, Jupiter DEX, NFT tools). The current count overwhelms the coherence of the set.

Completeness4/5

The tool set covers a vast range of Solana ecosystem activities: token operations, swaps, staking, NFT management, bridging, oracle data, identity registration, chat, escrow, subscriptions, and premium streaming. Major lifecycle operations are present, though some niche subdomains may have missing functions (e.g., detailed governance or lending management). Overall, it's comprehensive for the intended scope.
