Colombo-Stock-Exchange-CSE-MCP-Server
An MCP (Model Context Protocol) server that provides structured access to Colombo Stock Exchange (CSE) market data. This server exposes CSE API endpoints as MCP tools so LLMs and agents can query real-time market, stock, trade, and announcement data.

criticalQ13MCP Bridge Package Supply Chain AttackMCP10-supply-chainAML.T0054
Pattern "(?:mcp|fastmcp|langchain-mcp|llama-index-mcp)(?:>=|~=|==)?(?!\d)" matched in source_code: "mcp" (at position 96)
MCP bridge packages (mcp-remote, mcp-proxy, @modelcontextprotocol/sdk, fastmcp) are high-value supply chain targets — CVE-2025-6514 (CVSS 9.6) in mcp-remote affected 437,000+ installs. Always pin exact versions (no ^ or ~ ranges). Use lockfiles (package-lock.json, pnpm-lock.yaml, uv.lock). Never run `npx mcp-remote` without version pinning. Verify package integrity with `npm audit` or `pip-audit` before deployment. Reference: CVE-2025-6514, OWASP ASI04.
criticalQ2LangChain Serialization Bridge InjectionMCP03-command-injectionAML.T0054
Pattern "(?:from|import)\s+langchain.*(?:dumps|dumpd|loads|load)" matched in source_code: "from langchain_mcp_adapters.tools import load" (at position 81)
MCP tool outputs flowing into LangChain serialization pipelines must be sanitized to strip `lc` marker keys before serialization. Update LangChain to >=0.3.81 or >=1.2.5 which patches CVE-2025-68664. Never use secrets_from_env=True in production. Implement an allowlist via `allowed_objects` parameter on load()/loads(). Treat all MCP tool responses as untrusted data in LangChain deserialization contexts.
highK11Missing Server Integrity VerificationMCP10-supply-chainAML.T0054
Pattern "(connect|load|register|add)[_\s-]?(mcp|server|tool)(?!.*(?:verify|validate|checksum|hash|sign|cert|fingerprint|pin))" matched in source_code: "load_mcp" (at position 122)
Implement cryptographic verification for MCP server connections: (1) Pin server TLS certificates or public keys, (2) Verify server tool definition checksums against a known-good manifest, (3) Use package manager integrity checks (npm integrity, pip --require-hashes). The MCP spec recommends but doesn't yet mandate server signing — implement it proactively. Required by ISO 27001 A.8.24 and CoSAI MCP-T6.
highK15Multi-Agent Collusion PreconditionsMCP05-privilege-escalationAML.T0054
Pattern "(agent|delegate|orchestrat).*(?:invoke|call|execute|spawn)(?!.*(?:rate[_\s-]?limit|throttle|quota|max[_\s-]?concurrent|semaphore))" matched in source_code: "agent.ainvoke" (at position 1661)
Implement collusion-resistant multi-agent architecture: (1) Verify agent identity cryptographically before accepting commands, (2) Apply ACLs to shared write surfaces, (3) Rate-limit cross-agent invocations, (4) Audit all inter-agent communication with timestamps and agent IDs, (5) Baseline normal interaction patterns for anomaly detection. Required by MAESTRO L7 and CoSAI MCP-T9.
highK16Unbounded Recursion / Missing Depth LimitsMCP07-insecure-configAML.T0054
Pattern "(invoke|call|execute)[_\s-]?(?:tool|agent|self)(?!.*(?:depth|level|limit|max[_\s-]?(?:depth|recursi|iter|call)|count))" matched in source_code: "Invoke Agent" (at position 1547)
Add explicit depth/recursion limits to all recursive operations. Use iterative approaches where possible. Set maximum depth for directory walking (max_depth=10), tree traversal (max_level=20), and agent re-invocation (max_calls=5). Implement circuit breakers that halt after N iterations. Required by EU AI Act Art. 15 (robustness) and OWASP ASI08.
mediumK17Missing Timeout or Circuit BreakerMCP07-insecure-configAML.T0054
Pattern "(?:callTool|invoke|tools\/call|execute_tool)\s*\((?!.*(?:timeout|signal|deadline|cancel|abort))" matched in source_code: "invoke(" (at position 1668)
Add timeouts to ALL external calls: HTTP requests (30s), database queries (10s), subprocess execution (60s), and MCP tool calls (30s). Implement circuit breakers that open after N consecutive failures (e.g., opossum, cockatiel). Use AbortSignal for cancellable operations. Required by EU AI Act Art. 15 and OWASP ASI08.
mediumK20Insufficient Audit Context in LoggingMCP09-logging-monitoringAML.T0054
Pattern "print\s*\(.*(?:request|handle|process|tool|invoke|execute)" matched in source_code: "print(f"Loaded {len(tools)} tool" (at position 938)
Use structured logging that includes all five ISO 27001 A.8.15 fields: (1) WHO — agent/user identity, (2) WHAT — tool name and operation, (3) WHEN — ISO 8601 timestamp, (4) WHERE — server ID and correlation ID, (5) OUTCOME — success/failure and result summary. Replace console.log with structured loggers (pino, winston). Add correlation IDs for request tracing across multi-agent chains.
lowF4MCP Spec Non-ComplianceMCP07-insecure-config
Server fails MCP spec compliance checks: required:server_name; required:server_version; required:protocol_version; recommended:tool_descriptions; recommended:parameter_descriptions
Follow the MCP specification for server metadata. Include server name, version, and protocol version. Provide descriptions for all tools and parameters.
